Bit of a special case here but can be managed if you’re willing to keep up with it.
- copy /lib/systemd/system/plexmediaserver.service to /etc/systemd/system (creates an override)
- Inject
sleep 60 ;at front of the ExecStartPre and the ExecStart – careful of quotes & syntax.
It will slow it down but you’ll be able to run.
Make certain to systemctl daemon-reload after making changes.
