Why not just grab a USB WiFi 6 dongle, theres plenty available, probably with better antenna's than your card has, so better signal.
Because USB isn't as reliable a interface (compared to PCI-E used by M.2 A/E wifi cards) for reliable networking (due to things like power saving and higher overheads being problematic).
USB also has both power limits (typically 4.5W for USB3.0) and heat restrictions due to the form factor of most USB Wifi Dongles.
