Can I swap out the card with another make/model? If I don’t want to use a dongle and my OS doesn’t support the original one.
How do I know which will fit?

"Unauthorized Wireless network card is plugged in. Power off and remove it."
Very sly move, Lenovo!
Now I need special hard- and software tools to modify UEFI!
