Hide off-canvas hamburger menu on mobile view

[EchoRomeo]

I'm building a small XF forum that's very simple and doesn't include any navigation whatsoever. However, even after I deselect all navigation tabs under "Public Navigation," the hamburger menu for off-canvas navigation still shows up in mobile view. I can't figure out how to hide this menu, which is now empty when opened. Does anyone know how to do this?

Thanks in advance!
