Add a templated oneshot service and use systemctl to start it. The systemctl command is invoked with "--no-wait" so that it returns immediately because the "oneshot" nature of the service would otherwise wait until the command completes.
Note that because the service is a oneshot with RemainAfterExit=no (so we can multiply start it), it will go from "activating" to "dead" without ever appearing to be "running".
