Help with 5x 10x zoom while look throught Viewfinder (Can't change shutter speed!!)

Hi people, I have a small problem with the eos r7, it turns out that when I want to photograph the moon at night for example... I look and frame for example through the viewfinder, if I want to zoom 5x or 10x (MANUAL EXPOSURE) (M) if I want to control the shutter speed while I am in 10x or 5x zoom and I turn the main dial to change the shutter speed faster for example to get moon with details, remove light, etc... It does not work. What that dial does while it is zoomed is change or move the frame/focus point, and of course the moon moves up or down or right left... it does not let me control the aperture or shutter speed and it is frustrating. Is there a way that if I move the main dial while I am in zoom it does not really move the frame and if I control the light that enters and get the moon that I want? Some setting that I miss? I hope I have explained myself. Thanks

I am not an R7 owner, but I would suggest either setting these settings prior to zooming in or you may be able to set the rear screen to quick control, where you can adjust these settings after being zoomed in. Beyond that, I have no idea since I do not own this camera.
