AV1 HDR encoding not possible with Nvenc?
#1
Question 
I have been using Hybrid instead of Handbrake to encode AV1 videos using my RTX4070 as I like the fact that Hybrid allows more control of additional Nvenc  parameters than Handbrake does, but for some reason I can get Handbrake to encode a hdr video as hdr whereas with Hybrid it does not retain any data showing it is HDR and I am unsure why.

Is there an obvious setting I have missed somewhere?

I would really like to encode my hdr videos in Hybrid as I prefer it to Handbrake. I have searched various forums, and googled extensively, but have not found a solution. Or perhaps there is a way to add in the data using mkvtoolnix or something similar as I have the original HDR video created from MakeMKV (these are encodes of videos I own as I like to have digital copies as back up), so in theory, as I kept the same frame rate as the originals, would I be able to use hdr data from the original videos header?

I imagine it must be possible, as Handbrake is definitely encoding a hdr video as hdr video and doing so using the gpu, I just don't seem to have found a way yet to do this outside of that.

Thank you for any help in figuring out a solution to this,
