What specific laptops have and upgradable GPU?

I know that the range of laptops with upgradable GPUs and/or CPUs is limited, but is there a way to obtain a specific list of some? I've looked all over, but I can't seem to find anything indicating if the laptop has these capabilities, and I don't want to create a new thread for each individual laptop asking if it can be upgraded.

I'm wondering as to the requirement to upgrade the GPU, why not purchase a laptop with a high-end GPU already?
I'll suggest Sager/Clevo models to start as most (if not all) have the ability to upgrade the GPU

The biggest issue with upgrading a GPU in a laptop is heat dissipation. Most laptops allow for the designed dissipation of heat and not much more than that. Adding a more powerful GPU can double or even triple the heat the laptop needs to dissipate, oftentimes that cannot be accomplished simply due to design

Very few laptops have upgradable GPUs since laptops require fairly tight thermal, electrical and mechanical integration with the laptop itself. There were attempts at creating multi-vendor standards many years ago but AFAIK, they all failed to gain widespread adoption.

You will find modular mobile GPUs in high-end gaming laptops like Dell-Alienware but the modules are often vendor-specific and model-specific. They serve very little purpose beyond sparing the vendor the trouble of designing and warehousing multiple motherboard variants for every possible GPU configuration they want to offer.

Most of the low(er)-end laptops simply use their CPU's IGP.
