@Aaron M - Yes you need to contact your Global/User Administrator to reset MFA .
Here is steps which you can share with Admin.
Using Azure Portal:
- Sign in to the Azure portal with the tenant Global Administrator account.
- Navigate to Azure Active Directory > Users > All users > Choose the user you wish to perform an action on > select Authentication methods > Require Re-register MFA.
- Once this is done, the next time the user signs in, he/she will be requested to set up a new MFA authentication method.
