Overriding iPXE global default

By default the templates that ship with foreman are locked as they may be replaced during upgrades. I would like to override the iPXE global default and iPXE default local boot (possibly more eventually). Starting with the global, I cloned it so that my changes are distinct from the distributed templates. However I cannot figure out how to tell foreman to use this template instead of the existing default. I have since unchecked default and dis-associated the default template with everything that is shown in the UI. Thoughts?

Currently running 1.20.2 but will be upgrading to 1.21.x as we will need the shim script for iPXE mac address detection.

Found it under Administer -> Settings -> Provisioning
