DP MST Settings on Jetson TX2 NX

I need to set up the DP interface in an MST configuration to drive a GMSL3 serializer (MAX96853). This device supports up to four MST streams over the DP interface to drive four displays independently.

The display timing information must be set during initialization for each stream separately, since the topology must be preprogrammed by the SoC. The GMSL3 and GMSL2 DP serializers do not support topology discovery via the DP auxiliary channel.

I assume this should be configured in the Device Tree, as I found a similar configuration for DriveOS here:
https://developer.nvidia.com/docs/drive/drive-os/6.0.6/public/drive-os-linux-sdk/common/topics/graphics_content/Display_serializer.html

How can this be configured on Jetson TX2 NX?

TX2-NX does not support DP MST.

Also, you should refer to L4T document but not Drive OS…

Jetson is not running with Drive OS.
