I read the following "When a View starts with _ (underline) it means that it will not be browsable, ie it will not be able to access your content through browser requests."
I ran a test, created a View with the name of _teste and a action I called it. In the browser I entered the address of this View and the contents of it appeared normally, that is, it was accessed. But was not it for her not to be accessed by starting with underline in her name?
