Unable to SMC -stop damaged client, forced to uninstall

Morning, I've been looking at a few damaged SEP clients (12.1 RU-1 level currently) where it isn't properly communicating but a SMC -stop command will not stop the service, the only way to repair is to uninstall/reinstall. Is there a more forceful way then the SMC -stop command to pull SEP out of memory? Tamper protection is disabled so that isn't an issue.
