Upgrading Hardware - How to amend Kexts

Hi all,

I am going to be upgrading my wifi card on my HP laptop which is running Big Sur but what is the best way to update my Kexts without breaking the current system.

I was thinking of mounting my EFI, deleting it (so that it all runs off USB), then update the Kexts on USB, swap hardware.

The reason why I was thinking of doing it this way is that if there are any problems I can revert back my kexts and config using another computer. If I break the system EFI then I don't know how I would get into MACOS or update it....

What is the correct procedure to upgrading my hardware?
