Bug Description
Some Dell systems crash when disabling Nvidia dGPU with I+N configurations
As NV Linux driver doesn't now support RTD3, BIOS removed the code to prevent system crashes as a short-term solution This is for Linux as Nvidia's Windows driver supports RTD3.
In this workaround an _OSI string, Linux-Dell-Video, was used in BIOS as a workaround in Linux.
