I have seen posts about stopping the os_prober from finding any disk when doing a grub update by deleting the os_prober. However, I have a dual boot and want grub to see both my Ubuntu and Windows 10 partitions on my NVME drive, but I don't want it to scan my 10TB backup disk looking for a partition.
Thoughts?
Thank you in advance.

I have many installs, some obsolete and lots of partitions, but only 1TB. First thing I do is turn off os-prober and add only the boot stanza's I want into 40_custom. I include 40_custom in my backups.
sudo cp -a /boot/grub/grub.cfg /boot/grub/grub.cfg.backup
sudoedit /etc/default/grub
then add
GRUB_DISABLE_OS_PROBER=true
sudo update-grub
Then we copy Windows boot stanza from grub backup to 40_custom. Use your editor, example is with gedit. You can open backup read only, but need sudo to open 40_custom.
gedit /boot/grub/grub.cfg
sudo nano -B /etc/grub.d/40_custom
sudo update-grub
