Hardening modern iPhone against forensic tools

You don’t need an Apple ID or iCloud+ to perform this hardening. I just recommend it for convenience. If you’re supervising your device using a MacBook you will need an Apple ID for the initial download of Apple Configurator. Yes you can do this with your iPad as well. iPads with m-series chips are the most secure apple devices as they can’t even be accessed in a AFU state yet. As long as apple drivers/usb passthrough are working it should work on Qubes.
