GPU not accessible in Camera Raw 16

Since installing v16 of Camera Raw it no longer automatically accesses my addition GPU, an Nvidia Quadro RTX4000. It defaults to the Intel UHD Graphics 630. Scrolling through large numbers of photos and using any of the tools is extremely slow compared to earlier versions. I cannot find any options that allow me to select the Nvidia GPU in the Camera Raw settings. Photoshop v25 still allows me to select the Nvidia GPU, so why won’t Camera RAW. As a fall back I was hoping to roll back to an earlier version of Camera Raw, but I see that is not an option either.
