Delete VoiceOver on my Mac

Recent versions of MacOS install the system onto a separate locked, checksummed Volume. If you manage to break it open and delete parts of MacOS, the whole thing will not run, and you will be facing a re-install. Don't waste your time and energy doing that.

You can turn it off in System Preferences>Accessibility>Voice Over (for other than Monterey the exact location in Accessibility may differ) . Depending upon the macOS version you may be able remove it but that may mess things up. Why not just turn it off?
