Hi, Is there a way to detach dGPU from Retina MacBook Pro 15" late 2013 with it? iFixit.com only tore down base model which does not have dGPU so I can't tell this from their materials. I need to install Windows through Boot Camp and I don't need dGPU performance at all but I'd prefer better power efficiency which iGPU provides. Windows through Boot Camp can't switch between iGPU and dGPU like Mac OS X or disable dGPU without horrible hacks and it's easier for me to just extract dGPU all together. Is it possible?
