Tekton Dashboard OIDC

Is there a supported way to enable OIDC with Tekton dashboard? I found this link:

https://medium.com/octo-technology-morocco/secure-authentication-to-tekton-dashboard-using-oidc-36de9b3f8a7d

which describes a custom way of doing it. But I'd prefer not to have to create a separate custom deployment for this. If there's a way to modify the out of box ingress/deployment/service that would be very much preferred.

Thanks!
