Git Configuration of External Git Client Checkbox

Product: PowerShell Universal
Version: 5.3.0

Hey all, looking for a hand from some people who may have used the Git integration. I’ve been testing out a dev/Prod flow using PRs and Github so my production server updates when a PR is merged and things are working quite well, but i have struck one challenge Im hoping someone might have seen

I’m setting the Github params via the appsettings.json file and everything passes in, but I cannot find the parameter in that file, or env variables that sets the External Git Client checkbox - which I use for the auth method we use.

Below is what my config looks like and what shows in the UI. Anyone seen/know what needs to be put in appsettings.json for the External Git Client value to be enabled by the settings/environment and not manually in the interface??
