Identify-First with Custom Background and Email MFA

As per the title. I’d like all three options available (Identify-First, Custom Background, so a Custom Login Page and Email MFA) when users sign in.

However, it seems I need to use Classic Login to have Identity First, the New Login for Email MFA.

If I customise the login pages I get a message Email MFA is not allowed when customising the page.

Is there any way to have all three of these enabled, or is it going to become an option at some point?
