How to fake my laptop GPU?

This raytracing is an new GPU rendering addition that requires specialized hardware, as in specific RT cores found on the graphics card itself. It will NOT work on any hardware without those cores, and even if it were possible to trick the game into believing your GPU has raytracing support and to force your GPU into running the related calculations it would greatly lower your framerate to the point of unplayability.
