Bypass login page for "git-gateway"

Is it possible to disable the login page for the "git-gateway" backend?

The use case is to have the CMS secured via an external means, such as a reverse proxy, so that calls to the `.netlify/git/...` paths are essentially unauthenticated?

I'm specifically working on a "git-gateway" implementation using Cloudflare Workers with access secured using Cloudflare Access (although this could be more generic to allow any incoming JWT to be verified) so a Cloudflare Pages based static site can be set up with Decap CMS without any external dependencies and not require CMS users to have direct access to the git repository.
