 Under the hood enabled service in VM is signaled by file in /var/run/qubes-service. This can be used to implement almost enable/disable **per-VM** switch controlled by dom0. Adding support for systemd services is pretty simple:
 
-1.  Disable old service: `systemctl disable <service name>`
-2.  Create `/etc/systemd/system/<service name>.service` file containing:
