How setting AF for canon g7x ii

I just brough canon g7x ii and meikon housing. Could anybody advice me? When put the camera in housing, touch screen cannot workable. So how or what AF have to setting my camera? My problem is the small retangle AF frame is at the center of frame and I cannot move it, AF frame not automatic move to other point and cannot move by any button (I set single 1-point). so I can focus only at the center of frame. Thank you in advance for any advice.

Thanks for your advise.

That 's mean I have only AF point that have setted before put camera into housing. So if I would like to focus on subject at the corner of frame, I have to lock AF then recomposition, right.

Shooting through a flat port underwater, your corners are subject to significant pincushion distortion, so in general it's not a good idea to put your subject there in the first place.

in default behavior, the Ring Func button (left of the video record red button on back) can be hit, which then allows you to use the directional keys to select a non center focusing spot.   This might make sense when doing a tricky macro composition, but focus and recompose is usually faster.

If your housing doesn't give you access to the ring func button, you can probably reassign one of those that is available.
