TV account with SSO for TV mode

Hello, I am wondering whether something like this is possible:

Since TV mode is for… wall mounted TV, I’d like to avoid signing in with an account there.

We could have a View-only account with concrete username and password there, but since all of our other accounts are SSO, it would be nice to disable the login form altogether.

Anonymous access is also not ideal because we still want to restrict public access.

I’d like to know if you can log into a user account from a Super Admin account. Or even better, a TV account that you can switch to from any user account.
