Is there a setting in cameras that does not need any focus while zooming?

No. The lens is varifocal. That means the focus distance changes as it is zoomed. Parfocal lenses maintain focus with changing focal length. I don't believe there are any current fixed lens cameras using a parfocal lens. (Complexity, size cost...)
