Kernel extension already require a special developer certificate. You should explain to Apple what you need it for, then if your are accepted by Apple you get a new signing certificate including kernel Extensions. After that you can do "anything". With the notarized every app will be needed to be scan by Apple before. It's something a lot more painful than Microsoft Windows Defender which do the same (first launch of unknown app) for every app and maintained a worldwide database of signature of authorised apps.
