Most laptops come with soldered cpu's anymore unless you have a gaming laptop so you won't be able to change it out. You also won't be able to change the gpu either. Basically you are limited to ram and ssd upgrades on cheap laptops.
Usually storage/ram/wnic are the only real upgradable components for modern laptops,, socketed CPUs used to be more common and there were a 'few' laptops with swappable GPU, but certainly not that one. Since that's basically an ultrabook with U series CPUs you're generally stuck with whatchu got.
At least the ROG AMD Advantage is still on sale for $1300 at Best Buy
