You cannot. systemd is a service manager. When you tell it to manage
something that means it will start/stop/introspect/... it for you. But
if you manage the service on your own, outside of it, then it won't do
any of that.

Hence: either let systemd the service and then also stop it for you,
or do it yourself, but you cannot let it stop it for you but not start
it in the first place.

Sorry,

Lennart
