The Find My service must be disabled. A Mobile Device Management (MDM) solution must be used to carry out remote locking and wiping instead of Apple's Find My service. Apple's Find My service uses a personal AppleID for authentication. Organizations should rely on MDM solutions, which have much more secure authentication requirements, to perform remote lock and remote wipe.

Verify the macOS system is configured to disable Find My service with the following command:

/usr/bin/osascript -l JavaScript << EOS
function run() {
  let pref1 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowFindMyDevice'))
  let pref2 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowFindMyFriends'))
  let pref3 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.icloud.managed')\
.objectForKey('DisableFMMiCloudSetting'))
  if ( pref1 == false && pref2 == false && pref3 == true ) {
    return("true")
  } else {
    return("false")
  }
}
EOS

If the result is not "true", this is a finding.
