When NetworkManager is configured to not manage all interfaces, it's
perfectly fine to have the rest be managed by the standard nixos
wireless scripts.
I use
networking.networkmanager.unmanaged = [
"*" "except:type:wwan" "except:type:gsm"
];
to control everything using networking.wireless except for the mobile
LTE modem which only works with NetworkManager.
