    Since you already have the MFA enabled for you can set the Secondary/Alternate Phone Number for MFA by following the steps mentioned below:

    To add a secondary phone number:

    1. Sign in to
    2. Select your account name in the top right, then select Profile.
    3. Select Additional security verification.
    4. On the Additional security verification page, check the box next to Alternate authentication phone.
    5. Enter your secondary phone number in the text box.
    6. Select Save to save your changes.

    Ref: Manage your settings for two-step verification

    And yes, if the Primary Phone Verification is not available, you would need to manually select the option "Use a different verification option" to use the Alternate Phone for the verification.
    Ref: Get help with two-step verification


    You can also go directly on the following URL "MFASetup" and update the secondary phone number for Alternate number for MFA.
