Prohibit PIN authentication and force password authentication?
This was true with the Windows 10 desktop 1511 version, the setting didn't have any effect, but with the 1607 version that changed. I've verified this not that long ago.
I think the PIN element is part of Windows Hello for Business. I am not aware of a way to remove this if they are AD Joined.
When creating a PIN it may prompt to verify identity with a text or phone call, this part can be skipped if you have ADFS but a PIN would still be required to set up.
It's correct that Windows Hello is a services that is included in Windows 10 and that it's the cause of the PIN request and MFA promting. But if it's a Windows 10 desktop version 1607 or above that you are Azure AD joining you can actually disable Windows Hello for Business with a setting in Intune.
But for Windows 10 Mobile this setting will not have any affect since it's by design that Windows 10 Mobile devices will bypass this setting when Azure AD joining these devices.
- Btw. This is also true even if you don't use ADFS.
