I found on a Surface Pro 6 under Big Sur, my EN0 kept showing not built-in. I had to follow the steps to add the SSDT-RMNE.aml to the config.plist file under the ACPI section. Just use the Dortania tutorial, and then drop the file into the EFI/OC/ACPI folder once you download it from the link into your System EFI on Mac, then reboot. Most systems already have the Ethernetnull kext installed and line in OC plist file, so no need likely. Just verify it is already there like many are in the kext section. I tried adding the PCI using hackingtool method, but it would never identify it correctly and show built-in, no matter what PCI device I added to the line, it just shows as an ethernet and wireless device, but built-in never shows checked. As soon as I dropped that ssdt file and did the plist, rebooted, another ghost adapter showed up in the Network under the working one in Mac OS Big Sur. And iMessage started working immediately. Good luck. Thanks for the site, hope this info helps others.
