Contentlayer fit for public repo pulling in data from private repo

[coopbri]

My use case involves a public repo (Next.js app) with a section blocked behind an auth layer. I am trying to pull in content (MD & MDX files) from a private repo and load them into the app for authenticated users. Is it possible to use Contentlayer for this, or is something like next-mdx-remote, which has runtime (on-request) fetching, a better fit? I am mainly worried about the local artifacts contentlayer generates in the repo.
