Can HDMI output and CSI input be in pass-through mode without data conversion during AGX Xavier module transmission?

Hello!
We currently use two AGX Xavier module, One AGX Xavier module‘s HDMI output to FPGA,then transform from HDMI to MIPI signal by FPGA,which would be as input of other AGX Xavier module,and the resolution is 4KP60(420). Can HDMI output and CSI input be in pass-through mode without data conversion during AGX Xavier module transmission?
Note:we can guarantee FPGA processing that transform from HDMI signal to MIPI signal.

Current VI/CSI only support YUV and RGB888 format for this kind of use case.

We now use YUV420 format. Can HDMI output and CSI input be in pass-through mode without data conversion during AGX Xavier module transmission?
Look foward to your reply!

I don’t understand what’s the pass-through mode.
If it’s follow the MIPI CSI spec Xavier can support without problem,

I want to know whether the HDMI output has some data conversion. If yes, which configurations need to be disabled? What I need is no change in the data output.

I am not sure, but you may get help to check the tc358840 bridge that confirm working well on Jetson devices.
