Since Hybrid dropped support for 'FFmpeg (NVEnc)' on Windows systems with Hybrid version '2020.06.21.1'.
Hybrid has been using NVEncC itself to add HDR metadata instead of nvhsvp since '2018.04.08.1'.
Since you didn't attach a debug output or even mention what OS you are on I can't really say much aside from that if you are on Windows and you are using NVEncC you might need to update your drivers since NVEncC or use an older NVEncC version, because starting with version 5.10:
you will need newer drivers.
If you are on Windows and want to use 'FFmpeg (NVEnc)' you need to stick to a Hybrid version before '2020.06.21.1', but remember I only support the latest Hybrid version.
If you are on Linux, the only ways to add HDR meta data atm. are either using nvhsp or using mkv as container and add them through container tags (Config->Output->MKV Container->Matroska advanced video signaling).
-> share more details about what you are doing and what OS you are in and I might be able to help further.
