The idea seems to be trending in cosmology and it might offer a way out of some dilemmas, according to Michael Egnor:
Superdeterminism is the view that the outcomes of all possibilities — both inanimate nature and the human mind — are “baked in” to nature itself. There are two ways of understanding what that means. The first way is to see nature as a mindless machine running like clockwork without free will. As I’ve said, such a view is incompatible with human reason.
However there is another way to understand how the outcomes of all possibilities in nature are baked into nature itself. This involves the concept of a “block” universe and the Augustinian understanding of nature as a thought in God’s mind.
In general relativity, the universe is understood as a four-dimensional space-time manifold consisting of three dimensions of space and one dimension of time. From this perspective, the passage of time can be understood as a movement through the four space-time dimensions along what physicists call a world-line. The universe itself from its beginning to end can be understood as a four-dimensional block that includes time but is not in time itself. It is in this timeless block that Superdeterminism can be true without denying free will and without viewing the universe as a mindless machine.

Takehome: Michael Egnor: If we lack free will, we have no justification whatsoever to even believe that we lack free will. In a timeless block however, the future exists simultaneously with the past and present — but that does not mean that the future determines the past and present.
Mind Matters News offers a number of articles on free will by neurosurgeon Dr. Michael Egnor including
Can physics prove there is no free will? No, but it can make physicists incoherent when they write about free will. It’s hilarious. Sabine Hossenfelder misses the irony that she insists that people “change their minds” by accepting her assertion that they… can’t change their minds.
Does “alien hand syndrome” show that we don’t really have free will? One woman’s left hand seemed to have a mind of its own. Did it? Alien hand syndrome doesn’t mean that free will is not real. In fact, it clarifies exactly what free will is and what it isn’t.
But is determinism true? Does science show that we fated to want whatever we want? Modern science—both theoretical and experimental—strongly supports the reality of free will.
How can mere products of nature have free will? Materialists don’t like the outcome of their philosophy but twisting logic won’t change it
Does brain stimulation research challenge free will? If we can be forced to want something, is the will still free?
Is free will a dangerous myth? The denial of free will is a much more dangerous myth
Also: Do quasars provide evidence for free will? Possibly. They certainly rule out experimenter interference.
and
Can free will even be an illusion? Michael Egnor reiterates the freeing implications of quantum indeterminacy
Also, by Baylor University’s Robert J. Marks: Quantum randomness gives nature free will Whether or not quantum randomness explains how our brains work, it may help us create unbreakable encryption codes
We seem to experience the capacity to exercise free will yet it would be irrational to deny that the nature of the present has been influenced by what has gone before. Our apparent free will does not enable us to change the past.
The concept of a block universe is an intriguing one in which all possible events co-exist as one block and the passage of time is what we experience as we move through them.
Think of an old-style movie reel. If you stretch it out all you see is a sequence of static frames. Run it through a projector, however, at 25+ frames per second and you get a smoothly moving image on screen. In this case it’s the film that’s moving but, in principle, you could stretch the film out straight and then run the projector along it and still get a moving image – an impression of time passing.
Actually, Fred Hoyle touched on this in his SF novel October The First Is Too Late. His question was, if this is the case, who or what is moving through this “timescape” and doing the perceiving?
As I stated years ago when Sabine Hossenfelder, and others, first floated the idea of ‘superdetermism’ in response to the closing of the ‘freedom of choice’ loophole by Zeilinger and company, “Welcome to Christianity. Strict Calvinists have been arguing for superdeterminism, and against the reality of free will, for centuries.”
Of related note, although it is popularly believed in Christian circles that John Calvin rejected free will altogether, the fact of the matter is that John Calvin did not reject free will altogether but he had a nuanced, ‘limited’, view of free will that is not nearly as radical as is often popularly portrayed.
