You don't need to hide it so deeply, it can be added to your control panel add the control 'vehicle motion cues' and you can add a button which allows you to change it between on/auto/off.

I highly recommend people look through apple's accessibility features every major release they seem to quietly release some real gems.

They hid a whole app for sleep/chill/productivity/wellbeing sounds in there as well!

You can add it as a Control Center toggle as well which is useful for quickly enabling / disabling without digging through the settings

At this point the Accessbility preference panes are just crammed full with tweaks and tools – good if you need them, bad for discovery!
