Two Monitors - One Off-brand Graphics Tablet

Hey all, this is my first post to the Arch Linux forums so please tell me if I do anything wrong.

So I recently purchased a graphics tablet off of Craigslist because I wanted one and it was cheap. Didn't know I would be suffering multiple headaches over it. It works fine with a single monitor, but with two, ugh.

My main problem is that the way that my setup is configured is I have two monitors stacked on top of each other like so:

Whatever default driver is used (I think it's just libinput) works fine with the tablet. Problem is: when I go to write something on the tablet, the drawing is stretched 2x vertically because the tablet is mapped to use both monitors; the top of the tablet is the top of HDMI1 and the bottom of the tablet is the bottom of eDP1.

To try to solve this issue I experimented with the wacom drivers posted on the Wiki, but to no avail (the mouse didn't even move at all). I just don't think my tablet is supported by xsetwacom (yes I followed the wiki and found the tablet's "VID:PID" and wrote an xorg config for it).

Any thoughts on how to map the tablet to only one monitor without the wacom project?

Some related commands for those who care:

You can see that the tablet is 0b57:9091. Weird name because it is definitely some weird generic tablet.

As you can see it is using generic drivers (input,hiddev0,hidraw0), which is fine since I don't need any fancy sensitivity tracking or anything. Problem is I don't know how to configure them to map the mouse input to one screen.
