How to update Authentication Phone Number[for MFA] in Azure AD using On-premises user attribute?

Hi,
I am looking for a solution to update the "Authentication Phone number" attribute under Authentication methods in Azure AD user account using an attribute of On-premises AD user account. I have situation wherein users lost their old mobile number registered for MFA and are requesting to update the authenitcaiton method phone number manually as they were unable to login to portal as their MFA call/text is going to lost device. I wanted to know whether there is any attribute on On-premises AD User account that can be used to update/sync the "Authentication Phone number" in Azure AD.

Please share the references or solution for this. Thanks in Advance!
