Forget about it. You cannot do that. There is an uma version without discrete graphics. The discrete version is builded without processor igp power rail. Lvds connector gets its signals directly from dgpu...etc. There is no way to convert it to uma

That board can´t be converted from dsc(discrete) to uma. Missing some components to activate the integrated vga.

Do vga chip reballing or change a new one
