Upgrading a GPU internally in a laptop chassis is tricky because you need the power/heat/space to work for the range of possible products. And I like a CPU where you might design for a 35W CPU and that gives you dozens of options from 15W to 35W, the GPU range needs to encompass 100W (!) if the purpose is meant to allow configuring as a gaming machine. This will obviously affect cooling/power supply/bulk for all who buy the laptop and don’t want the gaming config. External GPUs have their own difficulties but I think it’s a less challenging design problem than “configurable GPUs [up to enthusiast/gaming/pro cards]”
