This question becomes inconsequential. I have free will and I don’t have it. I can predict some things, sometimes it works, sometimes it doesn’t. Life is predetermined, yes, but at the same time I can do stuff and my actions affect things. It doesn’t matter, I don’t think about these things.

The question of determinism only arises in the separated state, because of the inner conflict between ego and life. From this perspective, it is much better to accept the idea of total absence of free will, because the entity which you currently think is “you” surely doesn’t have it, and it will help it surrender to life.
