The component responsible for all the notarization nonsense and entitlements enforcement is not SIP, it's AMFI. You can disable it too with a kernel argument, I don't remember it exactly but it's something like "--amfi-get-out-of-my-way". This will reduce the security of your system approximately to that of Windows.
