Offering consumer one auth method, but backend requires another

Questions
1

Is the above possible with Kong?

For example, lets say we have a strategy to expose all our services using OAuth2, but one of the backend services we source data from requires JWT authentication.

Is Kong able to do that? Offer consumers one form of authentication, but communicate with a backend service on another method?

If so, where could I read about this?

Thanks

Maybe this doc helps?

You can use multiple auth method in AND, OR method.

I have read that, but I am not clear what I would need to do in order to expose a service as having one method, but communicate with a backend method using a different method?
