Turning off the volume bar

I have a Panasonic th-50px6u and I want to know is there any way to turn off the visual volume bar? I can't find anything in the regular menu but I know there are other menus I just don't know how to get to them, can anyone help?

I have never seen that choice in a menu. I do not believe that has ever been possible in a Panasonic.

I know there is a technicians menu that you have to know how to get into and I was hoping somebody can provide that information so I could look through that menu, I don't know if what I'm trying to do is even in that menu but I don't know until I can look.
