no not really. In settings I have only build in wifi listed. Normally if the secondary adapter is installed you have a choice of both.
I can see that device is detected lsusb:

hmmm thank you. I have not seen this. I tried it the install was successful with no errors but the interface for the USB dongle is not coming up. Could you suggest how to diagnose it?
All what I do is:
apt update
apt install git dkms
git clone https://github.com/gnab/rtl8812au.git
cp -r rtl8812au /usr/src/rtl8812au-4.2.2
dkms add -m rtl8812au -v 4.2.2
dkms build -m rtl8812au -v 4.2.2
but it fails on:
dkms build -m rtl8812au -v 4.2.2
Kernel preparation unnecessary for this...
