AC-8260 M.2 - LED outputs?

I am integrating the Intel Wireless-AC 8260 (Part Number: 8260NGW e.g. M.2 2230 card) into a new hardware design.

The cards basic functionality is working e.g. Wi-Fi, Bluetooth.

The problem I have is that the 8260 doesn't appear to drive its LED output lines i.e. LED1# (M2 slot pin 6) or LED2# (M2 slot pin 16). I have previously used various Intel cards, using the half-sized mini-PCIe format (6235, 7260 etc...) and each of these cards have always driven their LED output(s).

I have checked the 8260's product brief and it does not mention the LED output, whereas the 7260's product brief does.

Have Intel dropped the LED output facility from its 8260 cards?
