The display of vertex numbers/ID for a mesh does not show up in my installation of Max 2022 or any other version of Max I know of. As far as I know, this is not a basic feature of Max that can be toggled on and off and it would have to be scripted; there are some old scripts floating around that do that, but unless someone else had access to your computer and ran the script or maybe in the startup folder, not sure how you have this being displayed.
You are probably aware that for editable splines you can toggle on and off "Show vertex numbers" but the vertex numbers displayed have a completely different appearance than you show and it looks obviously like a mesh in your screenshot and not an editable spline.
Also in your screenshot there is a highlighted button called "Toggle Lpanel" that I am unfamiliar with and I see that you have some custom scripts, so maybe you have one that displays vert numbers and accidentally clicked on it?
Maybe someone else here is aware of a new feature or has a better explanation.
