ISO rises when zooming in?

Is there a way to compensate for the ISO going up when zooming in while on Auto ISO? I get low ISO at the wide end sometimes but when I need to zoom in for better focal length it goes up. Would ISO MFNR  be better in these situations, when I don't want to use a flash? Trying to avoid as much noise as I can while also avoiding distortion.
