How do I disable the PCI wifi and use only a USB wifi card?

I have a laptop with a built-in network card that stopped working. Until upgrading to Ubuntu 18.04, I could use a USB card instead, but in Gnome it seems I can not enable/disable the network interfaces one by one. If I connect to a network both interfaces try to connect, leaving the system without a working condition.
For reference, here is an old question on how to disable a network interface permanently, but that seems to work only for older Ubuntu versions: How to disable built-in wifi and use only USB wifi card?
Edit:
$ lspci -nnk | grep net

I think the method in the link is entirely valid. Let's identify the driver we need to blacklist for the internal device. Please edit your question to add the result of the terminal command:lspci -nnk | grep 0280 -A3

I think what I used to do is justrfkillthe internal PCI-e wifi card, and only then plug in USB, otherwise my laptop would get stuck.

@chili555 Thanks, I probably just didn't understand what to look for then. I edited to add the output oflspci --nnk. Greping for0280-A3didn't return anything

You ran the terminal command:
lspci -nnk
You found your wireless device:
Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b]
We search for the device ID 168c:002b and find, among others: https://wikidevi.com/wiki/Arcadyan_WN7811A
It reports:
Probable Linux driver ath9k
You can verify that this is the module that is loaded with:
lsmod | grep ath
If so, let's unload and blacklist the driver:
sudo -i
modprobe -r ath9k
echo "blacklist ath9k" >> /etc/modprobe.d/blacklist.conf
exit
You should be all set.

Note that the wifi card will not be unpowered but just unusable because the drivers will not load on boot. If you typesudo modprobe ath9kafter boot, the card will be usable again. To complete disable a pci device you should do it through acpi call.

sudo modprobe ath9k after boot, the card will be usable again. To complete disable a pci device you should do it through acpi call.– velix
