AV1 HDR encoding not possible with Nvenc?

[Selur]

Depending on where you live, HDR is available through:

• TV Stations,
  
• in cinemas,
  
• HDR Blu-rays,
  
• and self created content.
  

Sure, it's not as widely spread as SDR content, but it's not that rate.
Also, even if it was rare, that would be no reason to not use it.
