Enrolling corporate iOS devices authenticating with Setup Assistant

Question #1:

Intune with Apple DEP: We use the Company Portal for authentication, what is a pushed to the devices using Apple VPP.

The Company Portal is also set as required app, so the phones are "blocked" until it has been pushed to the device and the user has logged in.

I wonder if this change will impact us?

The majority of our user base has MFA enabled and setup.

Question #2:

Is this a general script or does it need to be customized for each individual user?

dict>

    <key>IntuneCompanyPortalEnrollmentAfterUDA</key>

    <dict>

        <key>IntuneDeviceId</key> -> Do I manually need to key in the device ID?

        <string>{{deviceid}}</string>

        <key>UserId</key> -> Do I manually need to key in the user ID?

        <string>{{userid}}</string>

    </dict>

</dict>

Hope this isn't the case, because we have over 5000 users...
