I'm looking to install a WiFi driver from this GitHub repo: https://github.com/morrownr/88x2bu-20210702. However, I'm really new to this sort of thing and could use some guidance. Any tips or step-by-step instructions would be greatly appreciated!

The simplest fix might be just updating your kernel. Which Linux distribution are you running?
If your distro is using kernel version 6.12 or newer, you might not even need that driver. A compliant, in-kernel driver for rtl8822/12bu chipsets is already available and works well. It's worth checking if your distro has updated to that version before going through the installation.
