Jetson TX2 DCDIRECT connections

I am working with Bruno Hexsel at Aeva on the design of the Jetson Tx2 carrier board for our application.

After looking at the TX2 OEM Product Design Guide and the P2597 carrier board schematic, I have a few questions:

1.The “DirectDC” input pins and associated circuit shown on page 4 of the P2597 schematic.

The OEM guide indicates these pins as “Reserved” but the actual carrier board has these pins going to a header.

What is the function of these pins?

It’s a kind of high speed debug interface, just leave it unconnected.
