@Chned Thanks for posting in our Q&A.
To clarify this issue, we appreciate your help to check where did you enforce the MFA. Did you enable the MFA in users in Azure AD portal or enable the MFA in the conditional access?
If you enable the MFA in users in Azure AD portal, it is suggested to try to disable it temporarily.
And if you enable the MFA in the conditional access, it is recommended to try to exclude the Microsoft Intune Enrollment and Microsoft Intune cloud apps from the MFA conditional access policy. Also, it is needed to set "Devices to be Azure AD joined or Azure AD registered require Multi-Factor Authentication" to "No" in Azure AD portal. These settings will bypass the MFA.
Hope the above information will help.
