I had previously upgraded the bios on this machine so I could whitelist future hardware.
The new card was easy to install: remove the keyboard by unscrewing 2 screws under the RAM trapdoor
Carefully remove the keyboard by sliding it towards the screen to uncover the lower tabs and unplug it, then remove the screws holding the palmrest and remove the palmrest carefully unplugging it.
The wifi card socket is on the right next to the M2 ssd socket
I removed pin 51 on the AC7620 with a dremel rather than using tape. Pin 51 is used to activate or deactivate certain card functions, including Bluetooth, and can be problematic on certain thinkpads. I did the same for my T430.
