Hi @Bedford, Jeana X ,
Thank you for posting your query on Microsoft Q&A.
The portal you are referring to which is linked to the admin centre is actually a legacy per-user MFA setting, which is required to be disabled when you are using Conditional Access, we have a matrix here highlighting the differences between Conditional Access vs per-user MFA - https://video2.skills-academy.com/en-us/azure/active-directory/authentication/concept-mfa-licensing#compare-multi-factor-authentication-policies
You can get an insight into MFA usage / registration via the "Usage & Insights" portal in Azure AD here - https://portal.azure.com/#view/Microsoft_AAD_IAM/AuthenticationMethodsMenuBlade/~/AuthMethodsActivity
Do let me know if you have any further questions, I would be happy to help!
