The simple answer is yes.

Drivers should be available from the software downloads section either thru the GL.iNet GUI, Luci or CLI.

That does NOT mean that your device is supported. You need to know the chipset inside. This link may help: https://wikidevi.com/wiki/Main_Page

I am unclear how well the GL.iNet GUI supports 2 adapters, so you may also need to use LuCi.
