ADV7611 with RGB 8:8:8  8bit output


using ADV7611 with 8-bit YCbCr BT656 mode VID_STD=0x8, PRIM_MODE_GRAPHICS, 60Hz, OP_FORMAT_SEL=0   I can receive 640x480 progres 60Hz video.

I would like to increase color depth received by uC from present 16bits to 24bits.

It could be done by receiving RGB 8:8:8 video.

Is there a way how  to configure ADV7611 (nonHDCP) to output 640x480 progressive video as RGB 8:8:8  on 8-bit SDR interface (P8:15) preferably with embedded sync?

HSync/VSync is acceptable too but requires HW change.
Or is there any other HDMI receiver that can output 8bit RGB?

Best regards,
