Add devices to ABM without physical contact
How can we add existing devices to ABM without the need to bring them in? We have iPads in stores spread around and we now want to enroll them in ABM and Intune. Is this doable without physical contact with the device? I know that previously it was a possibility to upload serials to ABM but that option doesn't seems to work anymore. It's not an option to have the stores send in their iPads just to get the serial uploaded to ABM.
