DisplayPort connector pin 14 on NX devkit

In the NX devkit schematic P3509_A01, p17, the pin 14 of DisplayPort connector is given net ‘SNN_DP_CEC’, and connected nowhere. But in some links, it says this pin should be grounded. So, why devkit float this pin? What should I do with this pin in my design?

Thanks.

It is not used on devkit, so it is floating.

Will the Jetson system work well if it’s connected to ground?

Thanks.

For Jetson, it is null. So it depends on the device as it is from device only.
