OpenIDConnect and oauth2 on same location

[hmoffatt]

Is it possible to protect a location with oauth20, falling back to OIDC if there is no token provided?

I found the documentation, here: https://github.com/OpenIDC/mod_auth_openidc/wiki/Single-Page-Applications#allowing-both-oauth-20-and-openid-connect

In my case I will have the users authenticated either by Cloudflare Zero Trust (token passed in header), or else use OpenIDC. Some servers will be protected by ZT and some not and I want to use the same config on both ideally.
