There's no Optimus on this machine. The nVidia card controls the Display. The iGPU is there only for the USB C.
@Alienware-Eimy, if the iGPU is wired to the USB-C output, then what happens when someone wants to use an external display connected via USB-C and play games on it? If there's no Optimus available, then that would mean that the NVIDIA GPU couldn't be used to accelerate content on the external USB-C display, which seems a very unlikely limitation for an Alienware system. Are you sure that Optimus wouldn't be used even in that situation?
Yes, it is a hardware limitation. The design is to prevent the AGA (Alienware Graphics Amplifier) from being disabled if the external display is attached to a USB Type-C device.
You need to use the mDP or the HDMI for external display usage, if you want the external to work with the Nvidia card.
