To remove a Jamf profile from your iPad when the company is no longer active, go to Settings > General > Profiles & Device Management, select the Jamf profile, and tap "Remove Profile."
If the enrollment profile is locked from the MDM then the only way to remove it is to Erase All Contents and Settings from Settings>General>Transfer or Reset iPhone> Erase All Contents and Settings. If the phone is still enrolled in ABM and assigned to an MDM then it might try to enroll again during set-up assistant. In that case you will need to figure out how to release this device and all others from the company's ABM.
