When I use the mosaic function , does the RTXA6000 support the output of 10bit color depth?

I’m using a RTXA6000.
I want to use mocasic to stitch the two screens into a 10-bit color depth output screen. I have tried many methods (including modifying the screen Edid information) and the output is still only 8bit. Does the current mosaic technology not support 10bit output?
