Merely as a "for your consideration," if you already have a build pipeline, rendering the in-repo docs and pushing them into Confluence could be a middle ground between "corporate overlords" and the workflow that works best for you and your team

I've lived this life first-hand, and it is refreshing after experiencing the vast open sea of half-assed Confluence sprawl, huge PDF design documents that aren't kept up to date with changing requirements, etc.

The other sibling comment regarding rendering documentation source to Confluence or <required external system> to keep the corp overlords happy is a great middle ground IMO.
