Turn off or change the Safari preferences shortcut (command + comma)?

Hi there dev_grrl,

Thanks for visiting the Apple Support Communities. Currently, the Safari shortcuts detailed in the Apple Support article Keyboard shortcuts and gestures in Safari on Mac - Apple Support cannot be turned off or changed. If you'd like to see that as an option in future iterations of macOS, we invite you to provide your feedback here: Feedback - Safari - AppleThis will ensure the teams responsible for those features are made aware of your request.

In the meantime, we can suggest seeing if you can change the Google Docs shortcuts, or try access it in a different browser.

Best.
