W530 hangs when iGPU is disabled and EFI started in dock

Description
W530 hangs (black screen, does not react on power button) on nouveau load when EFI booted in dock and iGPU is disabled in BIOS. When I boot EFI outside dock it does not happen even when I dock the laptop before loading kernel. It does not happen with our (nVidia) driver. It seems to be relatively new regression (I can reproduce it in 4.8.x kernels but I don't remember having this issue few months back).
