@Davis Henckel Thank you for reaching out to us. As I understand you are looking for Per-User MFA status in MSOnline module replacement, under MSGraph.
Based on response with my team internally on this issue, the new direction is to move away from per-user enforcement, and to leverage Security Defaults or Conditional Access to enforce MFA.
Also we advise to leverage the Authentication Methods and Authentication Strengths policies to control what methods a user can and must use, both of which have corresponding MS Graph APIs and cmdlets.
As a result, we do not have a programmatic way to manage per-user MFA besides the legacy MSOnline module.
Let me know if you have any further questions, feel free to post back.
