How to disable USB (for mass storage) on Mac OS Sierra and above?

Question

System administration

Good afternoon, how to disable / disable USB flash drives, disks and other drives in Mac OS Sierra?
Did it like this:

sudo kextunload /System/Library/Extensions/IOUSBMassStorageClass.kext
sudo mv /System/Library/Extensions/IOUSBMassStorageClass.kext ~/backup
sudo touch /System/Library/Extensions/
sudo reboot

Got

Failed to unload com.apple.iokit.IOUSBMassStorageClass - (libkern/kext) kext is in use or retained (cannot unload)."

- I tried to rename IOUSBMassStorageClass.kext
- I changed the date of the /System/Library/Extensions/ folder - I did it
via kextunload -b com.apple.
