10bit RGB via VDMA to Displayport

I have a sensor output of 10bit raw data which has been processed by custom demosaicing. I can display the data taking 8bit data from the original data using subset converter, eventually VDMA to DisplayPort.

I have a Monitor that also supports the 10bit color channel. After removing subset in vivado design and I set the VideoMode to 30 pixels. I could not find anything on 10bit RGB for DisplayPort configure. Is there any way to take the data without discarding the two bits and display it to the DisplayPort?

Thanks,
