We are rolling out SSO login via Entra for our Web applications (v12). I found the option in the LFDSSTS configuration page to hide the 'Windows Authentication' button and have done so. We eventually want to use only SSO login for gaining access to Forms and the repository.  I have been told this is done through edits to the 'login.cshtml' file on our LFDS server. 

Has anyone ever done this or can provide some insight into exactly what changes need to be made?
