If you need dedicated graphics and Linux and only want to screw with one machine I highly recommend you check out Framework mentioned in my comment edit above. Their 16 can be configured with integrated or dedicated either AMD or Nvidia graphics and can be purchased with no OS.
Purchasing with Linux preinstalled is problematic for some users because for most distros (though this is being actively worked on) encryption is set up during install not OOBE.
Lenovo ThinkPads, yes. Integrated graphics only.
Moving beyond integrated graphics in pre-builds is one of the larger issues in terms of availability.
For people who can only afford 1 and only 1 machine for everything, getting a version with an actual graphics card in it is going to be a necessity.
