1. Synology_HDD_db (GitHub)
A popular community script that modifies Synology’s internal HDD compatibility database so it will treat unverified drives as “certified.” 
• It lets your unsupported HDDs show up in Storage Manager without the “unverified/incompatible” warnings.
• Many users run it as a scheduled task so updates or reboots do not undo the change. 
2. Editing support_disk_compatibility flag
Some guides recommend SSH/terminal access to change a setting in /etc.defaults/synoinfo.conf (or via synosetkeyvalue) to disable the compatibility check:
support_disk_compatibility="no"

3. Pre-DSM install bypass
If you can’t install DSM at all due to unsupported drives, a trick is to enable Telnet at the DSM installation screen and run a loop that always returns the “installable” check as passed:
while true; do touch /tmp/installable_check_pass; sleep 1; done
Then after DSM is installed, you run the script or flag change to fully enable drives
