Does anyone have an idea how to activate advanced/more settings text box for Intel QSV profiles? I do have it on all other codecs but not on Intel QSV.

HandBrake version: 1.3.3
Operating system and version: Linux Mint 20
While the settings options are limited, there is a list of available options for NVENC, but the field is not available to enter them.
I'm guessing we can try incorporating them at the command line, but, in my mind, that defeats the usefulness of Handbrake (versus using FFmpeg directly).Experimental Linux support is available in HandBrake’s command line interface
