FriendlyArm recently updated the NanoPi M4 and added V2 in the name. In my opinion this is more a 1.1 but nowadays the product promotion works much better with general version step changes 😉
As I got the question the FriendlyArm NanoPi M4V2 should be fully compatible for this setup. The formfactor didn´t change. On their Website I found following changelog description

So you are good to go with the newer version but it would be helpful if you share your experience if you clone this setup with the new nanopi M4V2. Thanks…
