Why voice over recognition option disappears from 14.2

According to release notes, voice over recognition is introduced in iOS 14.

But I could not find it anymore in Settings, so I am not able to turn off image recognition.
Could anyone tell me why?
Seems although VoiceOver recognition doesn't exist Settings > Accessibility > Voice Over in iPhone 7/8,
the iOS 14 new features especially text recognition exist which is not stable and inconsistent with the behaviour on iPhone X/11/12,
and we do not have a way to turn it off on iPhone 7/8....
