GNOME Disks inherits UDisks' limitations, as it uses it under the hood.
With that in mind...

You should probably report this one upstream.  A fix would be
relatively simple to write, see [1] for the relevant line making the
Windows button insensitive.  The procedure
"gdu_utils_is_ntfs_available" spans only a few lines of code and could
easily be adapted to check for vfat instead.

Cheers
