It likely fits a m.2 slot and can be swapped out. Once the tiny rectangular casing is taken off, the card can be pulled from its position. Verify the key type the slot accepts. Updated sections now cover CPUs, Motherboards, and Memory.
If it isn't a M.2 as mentioned by WoodenMarker, you're essentially in trouble.
It might be a bit late, but you can swap out the M.2 card that came with it. Begin by taking off the 'antenna box' from the motherboard—there are two screws on the back. Next, remove the front screw facing the inside of the case. Once the shell is open, gently push the antenna sockets in. The sticker could create some resistance. After opening, notice the included M.2 card is secured on a stand. Unscrew it and lift it up as well, since there’s weak adhesive at the bottom. Handle the antenna socket connectors carefully. Now you can insert your own M.2 card. Repeat the steps in reverse.
