Use NVENC instead of VAAPI?

I'm running Emby 4.7.0.13 on a Fedora system with both an Intel iGPU and a dedicated nVidia 1050Ti.

I'd like to use the nVidia GPU, but Emby seems to default to VAAPI.

The reason I'd like to use NVENC is because the system sometimes hangs when using the Intel iGPU.

 

In Plex I can set something like:

HardwareDevicePath="/dev/dri/renderD129"

 

Is there some similar setting available for Emby?
