[HELP] Keep HDR metadata VPXEnc

[DevSker]

Hello,
I'm probably starting to be kinda annoying with so many posts
I have a little question, how can I keep a given content it's HDR metadata with VPXEnc? I've tried changing the primaries to BT.2020 but didn't work.

Since in VPX HDR MetaData is not keep in the video stream (like with H.265), but in the container it's a container option.
Configuring "Config->Container->MKV Tagging->Matroska advanced video signaling" should help.
