TinaCMS + Gatsby

Our Gatsby project generates about 150K pages. Looking at the docs it seems the team recommends Next.js over Gatsby.

From the Project setup guide:

Note: Building with Tina and Gatsby currently requires that you run a development server for content-editing. We recommend using Next.js for a solution with less friction.

Is there a way to use Gatsby in production mode and run an additional server to facilitate GitHub authentication and edits?
