You need to learn more about systemd. With systemd, you can have a local
override.

If you run "systemctl edit unbound.service" then it will open an editor
where you can add your "Restart=on-abort". This then gets merged with
the system-supplied unit. Your overlay is recorded in:

/etc/systemd/system/unbound.service.d/override.conf

Even if unbound is later upgraded, your local change persists.
