I don't think so. Free will is by definition, "free from god's will".
Can we do anything against god's will? No. By definition, god is the all knowing, all doing, all controlling, all regulating and all existing material with which everything is made. World is god. God is world. If you can do anything against him, you are more powerful than god. By definition it is not possible.
If you can't do anything against god's will, that proves there is no free will. If you can, your definition of god is wrong.
It is just fat, all determined already.
So, have fun.
