10bit encoding using GPU,

Please improve 10bit encoding using GPU, at the moment you dont support 10bit export, I have tried for the last 4-5 days to keep 10 bit all the hdr rec2020 and use hardware encoding which reverts back to software encoding which is no good very slow , 10bit 4k with hdr rec2020 is the way forward and include in you adobe media centre + adobe premier pro for a new pre-set for this, when I select x265 custom pre-set and select main 10 , tier high, rec2020, hdr, and include hdr10, straight away I receive a message , your system hardware does not support hardware acceleration for the current settings , I know it does Because I use a program called StaxRip
which does this and keeps all metadata for 4k 10bit x265 NVidia GPU acceleration. please could you create a complete new 10bit 4k x265 support for GPU encoding, I will attach a file with the issue I am facing, and I am not the only one a lot of customers are facing this issue , also
I got the info about 10bit export not being supported from adobe community forum, so please could you improve this. Thanks
