Disable overtype editing mode?

The Insert key on my keyboard is very close to keys that I use a lot (Backspace, Delete, Home, End). I have no use for the overtype (replace, overwrite) editing mode. So I disabled the Insert key in the Windows 10 registry using Sharp Keys. That was OK until recently but now I am using an app that relies on using the Insert key a lot.

Is there an option or hack I can use to completely disable the overtype edit mode in em Client? It’s what I don’t need and re-configuring the keyboard system-wide isn’t a great way to disable it.
