In some cameras, there's not much control of aperture. A work-around is to increase the ISO number, a.k.a. the sensitivity to light. This will force the camera to use a smaller aperture.
There may be some benefit to forcing the camera to focus on some point in the distance.

A short focal-length on a small format camera would help, if you used a smart phone camera you already have that.
You could also back up a little and crop into the frame. Depth of field gets a lot shallower as you get closer to the subject so backing up a little can make a big the difference.
