Are Awakened Zoan users able to change form?
I don't believe Oda has told us yet, and with how nebulous the definition of what makes for an "awakened" devil fruit user is, without canon stating one way or another there's not really any way we can solidly theorize a yes or no. I would presume that they would retain their ability to transform back and forth because that would make Chopper kind of lame if it didn't (but he'd be a pretty good golfer, because he'd lose all of his points [insert rimshot]), but again, without canon describing it we can't say definitively one way or another.
