Can rtx be completely turned off while playing with new assets/textures turn on?

Portal with RTX features full ray tracing, it is not an option to turn off. There are many different options in the graphics setting however, for DLSS, resolution etc.

go to your library and click Portal

it turns out RTX assets have been successfully stripped and turned into a mod so now people can play Portal with new graphics without the hog that is RTX. Thank you.
