How to disable the option which lets you add 3rd party authenticator app in MS / Azure Auth app:

Would like to remove this encircled option which says - I want to use a different authenticator app.

It's for security purpose since it lets you add open source auth apps and perform MFA.

An option is not available to turn this off yet. As a workaround use Intune or another MEM to block other authenticator apps.
