Jetson TX2 carrier board LED usage?

Hi

Is there any GPIO pins from Tx SOM to turn on/off the LEDs on Carrier board?

I found LED1. LED2 on carrier board, but there is no matching Jetson Tx2 pins for those pins.

What are LED1_L(CR4), LED2_L(CR3) pins of M.2 key expansion slot for?

No GPIO from SOM for these two LEDs. They are reserved for customers’ M.2 device design.
