I have some ideas in mind but it would prevent running the template to configure it, I guess you might need to run the template for a good reason occasionally?
Maybe just change the template name and tag it with ZZZZZZZZZZZ in front of its name 
or change the color? The idea is to not have the template name in your way, so you can’t mix things up.
You could use this Automatically restart a qube on stop but instead of starting the qube, it would stop it. If you want to use the template, you would need to manually stop the systemd service.
