Well .... If I you're presenting me a choice I would take the volume-label,

It's not possible using the volume label, unfortunately. When a file path is
given, the system uses the volume GUID to refer the volume that were
assigned to a drive letter. Moreover, a FAT/NTFS volume label is technically
a file, so there's no way to access a file without knowing the volume
location first.

I googled and found a code-example to how to change the drive letter, which
I have not tested yet, but I already get the feeling that that will bump
into the same "admin activity" restrictions too ...

I'm guessing your Windows user account is not a member of the Administrators
group?
