I don't think there is a way to disable an individual keyboard device in Windows. There may be an option in the laptop's BIOS to disable the build-in device, though in almost all modern laptops this is a long shot.
Generally the keyboard will lift out, and the cable to detach is obviously going to be the one connected to it.
