This is primarily meant to be done by daemons themselves, and I'm really
not sure if it works when done "externally" from a .service – but worth a
try:

ExecStart=@/usr/bin/myservice @myservice --option --option
KillMode=none

(The two "@"s have different meanings – the first one is documented in
systemd.service, the second in RootStorageDaemons.)
