Tamperproof CubeID with Here4 blue

I am currently trying to tamperproof a production aircraft to get a Declaration of Compliance with the FAA. As part of the DOC, you have to fail each individual field of Remote ID and make sure the aircraft won’t arm. The aircraft will give me an arm failed error pop up but I am still able to force arm. Any ideas of how to make sure you can’t force arm an aircraft?
