My last adapter uses rtl8812au so I installed from a Github repo and added it to dkms. I just got a new adapter that uses rtl88x2bu driver. I found that driver on Github so I installed it. Currently I have both adapters plugged in because I needed internet to install the new driver. Since I'm not going to use the old adapter anymore, do I need to uninstall the old driver from dkms?

You should not need to uninstall the old driver unless it's causing issues. If you want to uninstall the old driver to clean up your system, I would try this command

dkms status

You may see some results like this:

8812au, 4.2.2, 4.15.0-43-generic, x86_64: installed
nvidia, 390.77, 4.15.0-29-generic, x86_64: installed
nvidia, 390.77, 4.15.0-43-generic, x86_64: installed
rtl8812au, 4.2.2, 4.15.0-43-generic, x86_64: built
rtl8812au, 4.3.8.12175.20140902+dfsg, 4.15.0-43-generic, x86_64

From here you can see which drivers are installed, so remove them by typing (Replace 4.2.2 with your versions)

sudo dkms remove 8812au/4.2.2 --all
sudo dkms remove rtl8812au/4.2.2 --all
sudo dkms remove rtl8812au/4.3.8.12175.20140902+dfsg --all
