Custom exposure and focus at tapped location on camera view

I am using iPad pro11 front camera and device type is trueDepthCamera. Is there a way for a user to tap on the live view (AVCaptureDevice) and then focus at the tapped point.
Also i want to set custom exposure on the focus point.

So is there any way to change the focus as well as exposure to the tapped location for front camera for iPad 11 pro.
