For the moment, in the “storage” tab it is possible to configure a drive with scan “at boot” or after 2, 3 … 8 hours.
Even with the “8 hours” option for example, if I do a reboot (or several in case of reconfiguration of my server), the drives are systematically scanned even if they were scanned half an hour before (and without adding an album).
My roon server is under win10 and my files on a nas (samba network).
The wish is no scanning when the library is up to date and no changes have been made.
