How to remove BitLocker encryption for a volume that does not have a drive-letter

In Window 11, I can see all my volumes and their BitLocker status with this command:

Manage-bde -Status

And on a certain computer I find several volumes with BitLocker protection “active”, but instead of a drive-letter I get a hard-to-type volume-name like this example:

Volume "\?Volume{46hhhhhh-dddd-dddd-dddd-c0hhhhhhhhhh}" [WINRETOOLS]

I tried to find the syntax online, how to remove the encryption, but could not find details.

For a volume with letter, it goes like this:

Manage-bde -off C:

I tried to guess, but did not get it right at first.
