Hi Joe,
Hope you're doing well.
As far as I know, it is possible to move the file share from the Hyper-V Cluster File Share role to a Hyper-V VM.
Due to the simultaneous involvement of both network and cluster components and limitations imposed by the forum, I am unable to test this process in my testing environment.
The best way is to go to the Microsoft Customer Service Center to open a Premier-level case so that with their permission level and resource, Microsoft could provide you with better help on your request.
Best Regards
