@tarouchabi-7271Thanks for posting in our Q&A. From your description, It seems we have some questions about user enrollment for BYOD.
In General, users can enroll their personal devices for Intune management, know as "bring your own device" or BYOD. There are three options for enrolling users:
- App Protection Policies give you the lightest BYOD experience, providing management at an app level only. However, if you want to also secure the device with a 6-digit complex PIN, you can use these policies along with User Enrollment.
- Device Enrollment is what you may think of as typical BYOD enrollment. It provides admins with a wide range of management options.
- User Enrollment is a more streamlined enrollment process that provides admins with a subset of device management options. This feature is currently in preview.
User Enrollment is created and designed by Apple to facilitate an enrollment and management scenario for Bring Your Own Devices (BYOD). That enrollment and management scenario requires Managed Apple IDs. Managed Apple IDs are a type of Apple ID that is available for use through Apple Business Manager and Apple School Manager. They are owned and managed by your organization. Those Managed Apple IDs are used to create an additional user identity on the device and can live perfectly alongside personal Apple IDs.
We can check if we have managed apple ID for our organization. If yes, we can try user enrollment with the steps as below:

However, if there’s no managed apple ID, we can consider the device enrollment method for BYOD instead.
Hope it can help
