Help with iOS Device Enrollment for VIP Users

Hello,

I need assistance with enrolling corporate iOS devices for a group of VIP users. These devices are not registered with ABM or DEP and are already in use for personal and work purposes. I cannot use a Mac or Apple Configurator and want to avoid user enrollment with the Company Portal, as it won't be supported after iOS 18.

Current Setup:
Enrollment Profile: Device enrollment with Company Portal [Priority 1]
Groups: VIP-MDM-POC (Security group, assigned type)
Restrictions: VIP-MDM-iOS-POC [Priority 1], (MDM: Allow, Personally owned devices: Allow)

Process:
Devices are running with personal Apple IDs.
Downloaded Company Portal from the App Store and authenticated with corporate credentials.
Devices are automatically tagged as corporate.

Issue:
The Hardware tab shows the enrollment profile attribute as empty.
The Enrollment tab shows Profile Name: VIP-MDM-iOS-POC, Profile Type: Device Type Enrollment Restriction, State: Succeeded.

Questions:
How can I confirm the type of iOS enrollment if the Hardware tab shows the enrollment profile as empty?
Is there a better or easier way to approach this task?

Thank you!
