Generally there isn't, at least not for referencing unit options.

But for unprivileged access to pidfiles the usual approach is to create a
dedicated subdirectory under /run¹, either using RuntimeDirectory= or a
full tmpfiles.d config, and tell the service to use
"/run/myservice/myservice.pid". It might be simpler than touch+chown, and a
bit cleaner.
