Prevent systemd unit from starting if a certain other unit is running
I have two systemd services application.service and feh@.service.
application.service is enabled and usually running.
feh@.service is not enabled and started only manually and has a Conflicts=application.service entry.
I want to achieve, that if application.service is running and I start an instance of feh@.service, that application service terminates.
This is currently working due to the Conflicts=application.service entry mentioned above.
However, a data synchronization service periodically restarts application.service via systemctl restart application.service remotely.
I would like this to fail if, and only if, feh@.service is running.
Currently this will shutdown the feh@.service instance and start application.service.
I could not find anything related to this in the official documents of systemd.
Background info:
I cannot let the remote service check for feh@.service because this only exists on a few machines (it is an exceptional configuration) and is not part of the usual infrastructure.
I also do not want to stop the service, since it also controls other devices that may not run feh@.service.
