Is there a way to hide realm from endpoints, JWT issuer, URLs advertised in the well-known endpoint etc?

Instead of
https://mydomain.com/realms/master/protocol/openid-connect/token -> https://mydomain.com/protocol/openid-connect/token

Likewise the response of .well-known/openid-configuration should not have realm
{
issuer: "https://mydomain.com/realms/master,
authorization_endpoint: "https://mydomain.com/realms/master/protocol/openid-connect/auth",
token_endpoint: "https://mydomain.com/realms/master/protocol/openid-connect/token”,
….
}

Issued JWT:
{
"exp": 1652818065,
"iat": 1652817765,
"iss": "https://mydomain.com/realms/master”,
….
}

FrontendURL and the various related settings would not accomplish removing or /realm/{realmname} pattern from the url and it doesn’t seem feasible to achieve this without requiring edits in the Keycloak source code.
