As far as we know all matter obeys the laws of physics and our brain is no exception. Even if you want to suppose quantum effects are present in the brain (unlikely), that would at most impart some degree of randomness. The real nail in the coffin for any potential new scientific discovery that could cause free will is that this would have to entail some localized overriding of the currently known laws of nature to work - your motor neurons, or their inputs/etc, not being driven by chemistry but rather by this new "force" overriding chemistry. The problem of course is that no-one has ever observed the laws of chemistry not being observed, not even once, in our brain or elsewhere, which seems a major problem given that "free will" is subjectively happening non-stop. So, while it's not inconceivable that some new force/whatever might be discovered that controls matter in ways we've not seen, the real problem is that in this case there is no problem to solve! It's not like postulated "dark matter" invented to solve a problem with gravity ... in the case of brain/body function there is no mystery to solve, and no need for new physics - our brain/body appears to operate entirely under the control of the currently known laws of nature, which doesn't leave anything for undiscovered physics (or dualistic "souls") to control!
