How do I delete a /System/Library kext in MacOS Monterey

I've tried

csrutil disable

csrutil authenticated-root disable

mount -uw /Volumes/MacintoshHD

cd /Volumes/<DiskName>/System/Library/Extensions

rm -rf rm /Path/IOAudioFamily.kext

rm -rf /System/Library/Caches/*

Which worked in previous versions, but these do not appear to work in Monterey
