Welcome to the community, @Jorn_Bressem.

Please provide more context and information about your setup and the problem you have.

I’d like to help, as I also have a M1 macbook pro. But I’m confused, the disk mounts and is seen by the finder, right?

If so, the path to the mount point is /Volumes/. Is that not what you are looking for? IF it’s a roon core thing (I run my core on a rock, so I am not sure), could you mount it the old fashioned unix way?

maybe something like this:

*plug drive in
umount /Volumes/
mkdir musicMountPoint
mount_exfat /dev/ musicMountPoint

Then when you CD into that directory, you are actually on the external disk.
