DP Alt Mode on Jetson Orin Nano

We are trying to get the DP Alt mode working on our custom carrier board for Jetson Orin Nano 8GB.

I have verified the setup with USB PD protocol analyzer and USB PD messages look okay. DFP and UFP are managing to enter alt mode and configure the connection.

But I am getting the following error on Jetson and display out is not working
On connect:

On disconnect:

On disconnect error is listed in the known issues and also appears on Devkit.

What could be the issue here?

Thank you!

DP Alt mode is not supported on any Orin platform.

Thank you for the reply @WayneWWW

Is it a hardware constraint or is it a software constraint/not tested?

This is never in the plan of Orin display.
