Ummm...drones are NOT ‘piloted’.
They are remotely operated, aka ‘remotely piloted’.
‘Piloted’ denotes a manned cockpit, and the MQ9 definitely IS also an autonomous drone.

The US Air Force disagrees:

No mention of an “autonomous mode” for the MQ-9 Reaper:

Autonomous drones are coming...perhaps you are thinking of the XQ-58A “Valkyrie” or the Air Force “Project Venom”:
