The Asus Zenbook Duo (UX8406MA) has a keyboard which can be placed on the laptop to connect it via USB, or can be removed from the laptop to reveal a hidden secondary display in which case the keyboard operates via Bluetooth. When it is placed on the secondary display to connect via USB, it emits a keypress for a wireless disable. This causes the rfkill system to be activated disconnecting the current wifi connection, which doesn't reflect the user's true intention. Detect this hardware and suppress any wireless switches from the keyboard; this keyboard does not have a wireless toggle capability so these presses are always spurious.
