What type of renderer is utilized for graphics rendering in Dell MUXless design laptop?

Issue

DRI_PRIME=1 is an environment variable used in Linux-based systems to offload graphics rendering from the integrated GPU (IGPU) to the discrete GPU (DGPU). This is often used in laptops or desktops with a dedicated graphics card alongside an integrated graphics chip.
In certain MUXless design laptops, the video output to the integrated display is from the Intel graphics and more intense graphics work(rendering) is off-loaded to Nvidia graphics. However, when "DRI_PRIME=1" is utilized, the renderer used is not the hardware-accelerated renderer, but rather the software renderer.
