OpenApi and custom ControllerFeatureProviders

[csuzw]

I'm using a custom ControllerFeatureProvider to exclude certain controllers from my API (and I'd like to go further and be able to exclude certain endpoints from a controller but not worked out a way to do that yet!). This works and the excluded controllers are not reachable. However I've noticed that the OpenApi docs that are generated still include the excluded controllers. Surely the OpenApi stuff should respect the ControllerFeatureProvider? If not, for whatever reason, is there a way to exclude controllers/endpoints from the OpenApi docs without using attributes/touching the actual controller code?
