How to use a different puppet configuration (e.g. strict_variables)

Hey, I have set `strict_variables` (https://puppet.com/docs/puppet/4.10/configuration.html#strictvariables) to true on the puppetmaster. Now I also want this setting to be there for the octocatalog-diff run. Unfortunately I couldn't figure out how I could do that. The only think I could think of would be to add a bootstrapping script which creates a puppet.conf with that setting. But this doesn't feel right :)

Does someone has an idea how I could do that?
