I have latest blender 4.3.0 ,but does not exist this feature.
Do you mean the Viewport Overlays menu/popup, or the Diagnostics options (“Sealed objects”, “Doubled Vertices” and so on)?
Overlays are showing to me, I downloaded 4.3 a few days ago (which is still beta, not latest):
As for the diagnostics, as far as I know, they don’t exist yet. The image you’re showing is from a proposal that Andrew Price showed at the Blender Conference. It is some things he thought would be useful, but I don’t think they’re currently implemented or working.

As explained here:
The Diagnostics panel is custom UI for proposed features. If the proposal is accepted by the Blender developers, official Blender builds may incorporate the features.
