[keycloak-user] Customize OpenID Endpoint Configuration

Hello, I am deploying Keycloak behind a reverse proxy, and do not want others to know where it is actually located. Can I customize the OpenID Endpoint Configuration information presented in http://[KEYCLOAK_ADD:PORT]/auth/realms/demo/.well-known/openid-configurat... So that I can present the login page at the address of the reverse proxy. Thanks, Yang
