I have 2 similar problems which wouldn't be solved by disabling os-prober.

The common characteristic is wishing to probe all operating systems
residing on on a specific physical device. I multi-boot. There may be an
OS on any number of mounted devices (flash drives etc) which I do not
wish to probe.

I do not know any way to tell os-prober to limit the set of probed devices.
I guess you could edit /etc/grub.d/30_os-prober to filter out unwanted
devices from os-prober output with grep or so.

GRUB_OS_PROBER_SKIP_LIST? It's mentioned in /etc/grub.d/30_os-prober
and /usr/sbin/grub-mkconfig.

Yes, it is described in <https://www.gnu.org/software/grub/manual/grub/grub.html>.

‘GRUB_OS_PROBER_SKIP_LIST’

List of space-separated FS UUIDs of filesystems to be ignored from os-prober output. For efi chainloaders it’s <UUID>@<EFI FILE>

But it allows to exclude only known filesystems.
