I mean, free will isn't to be believed. But if you wanna, be my guest. If quantum mechanics is to be believed, then the model is certainly probabilistic at best, so you'll have enough wiggle room for it.
Oh don't you know that acts of free will only take place in the subset of chains of cause and effect that can be traced to the (decoherence-induced) collapse of a quantum state, and also just happen to turn out to be perfectly randomly distributed samples of the particular distribution quantum physics predicts for that situation?
