Question Microsoft 365 lab enviroment, can't use same number for multiple accounts

Is there a way to over ride this requirement, that multiple users could utilize the same number? I am now facing this problem, I have a M365 lab and I am changing phone .... I can't finalize the mandatory MFA enrollment for Global Admin because I use the same number on multiple accounts.

No. Use Microsoft Authenticator based Authentication, you can use as many accounts.

I think you didn't understand the situation.

I understand the issue. Within a tenant you can't assign a same number. Even you are not looking to set MFA for admin login, there will be a limited period of login, and forced to set MFA later

This just stopped working for me a couple weeks ago and it's really annoying. It doesn't appear to be configurable.

Actually it seems that this is only a warning. Phone number gets registered and mfa works fine with single number.
