I think your position represents a paradox then. If you “choose” to act, that choice is either of your own volition, in which case it is an example of true free will, or it is predetermined in which case it isn’t a “real” choice. Both branches represent a contradiction with your position, no?
Regardless, since you don’t believe in free will, you are either covered by option 2 or 4, depending on whether free will is real or not. How you choose to act doesn’t affect whether it exists or what you believe to be true.
