Most laptops can have their components swapped out. I've upgraded my ram [4->16gb], swapped out the slow non-nvme 128gb m.2 boot ssd for a 2tb nvme ssd.
I used a cheap m.2->sata tray in my laptops second slot with the 128gb ssd and macrium reflect* to mirror the old boot disk to the new ssd.
Next up I'm going to get a 4tb data ssd to replace the 128, and swap out the laptops 60hz display for a 144hz display.
Unless the laptops your considering have soldered data drives, are under unusually stringent after care plans (enterprise), or you don't want to mess with hardware these are pretty straightforward tasks. You can probably Google (laptop model) ssd swap site:YouTube.com and watch some one go through the steps. If YouTube doesn't have anything replace YouTube with reddit.
