Disable local login with SAML

True

Yes, I know it, the auth service is an internal ADFS. But my question is not about SAML nor ADFS since the external login works perfectly, I really like it.

I would like to know whether there’s a way to enable only one auth source in an account and disable all the others or with other words, disable local login on the users who have working SSO.

I understand that it can happen after a login attempt only, it wouldn’t be a problem.
