Note:

CTRL-EVENT-REGDOM-CHANGE changes as the connection is toggled on and off. Think everything is fine on that front. I think all the variables for wpa_supplicant.conf are passed across dbus from NetworkManager, I can't seem to find any temporary file within /run/ that has any mention of the wifi connection.

Think the easiest path would be for netplan's systemd-network backend to populate wpa_supplicant.conf with a country_code entry from within the 'wifis' section of the yamal file, that would be the equivalent to how RaspOS handles setting up it's wpa_supplicant.conf file.
