Getting Chrome to use nVidia dGPU for webgl and Intel iGPU for videos

Yet another intel/nVidia/chrome thread....

I managed to get my chrome browser to accelerate youtube videos using the onboard Tiger Lake UHD GPU with simply

 LIBVA_DRIVER_NAME=iHD   google-chrome-stable 

I had tried many times before unsuccessfully, somehow it works now

I can also get Chrome to run on the nvidia GPU with

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia  google-chrome-stable

Is there some magic setting by which both of these can be combined in one session?

The chrome://gpu page lists both GPUs - is there a way to tell chrome to render and similar videos using the Intel and use the nVidia for regulatr openGL stuff?

Surely since the video decoding is via vaapi unrelated to OpenGL, this should be possible?

Thanks in advance

Seperate browsers/browser profiles is going to be the most painless way to do this I'd assume
