HifiBerryOS external wifi

Peoples,

I have an external Ralink RT5370 USB 2.0 wireless adaptor that I used on a different Raspberry Pi, but would like to use it on my HIFIBERRY DAC+ PRO XLR with a Raspberry Pi 3b+.  I have the Pi in the metal case so need an external WiFi solution to extend range.

My question is how do I configure this adaptor under HifiBerryOS?  How would I disable the internal wifi as well (wlan0)?  I see that the drivers are already installed for my device.  The device is detected as well:
