This is how checkboxes used to look before 1.52, but It's currently not possible. You can easily recreate your own checkbox (e.g. #3351).

I think the ultimate aim is that we have a way to rewrite/customize some specific "symbols" (checkbox, tree node markers etc.) see https://github.com/ocornut/imgui/issues/6517#issuecomment-1596865541
