As stated by mike, the M2000M is not officially supported on these systems. Nvidia drivers block unsupported hardware combinations for mobile GeForce and Quadro hardware (read: if no variant of your laptop ships with your new GPU, drivers won’t install).
You’ll need to extract the driver installer and edit the .INF file to force Windows to install it on your new, officially unsupported hardware configuration. Also, you’ll need to disable driver signature enforcement (or w/e it’s called) because you’ll basically install a driver that’s been tampered with.
How? That’s an important question I can’t answer right now, but hopefully you’re willing to go ahead and search the internet for “mxm gpu inf mod” and find stuff like [https://null-src.com/posts/nvidia-notebook-driver-inf-mod/post.php|this].
Best of luck. Please do report back.
