64MP Quad-Camera independant focus?


I’m thinking about buying the 64MP Autofocus Quad-Camera Kit (64MP Autofocus Quad-Camera Kit for Raspberry Pi - Arducam) for a robotic project.

However I will need to independantly set the focus for each camera (each camera will have a different focus). Is it possible?
I had a look at the documentation and the github code to control the hat, and it seems to me that the hat acts as a single camera which would empeach me to specify independant focus parameter for each camera. Am I wrong? Is it possible?

Thank you for your help

Does anybody has tested this camera shield and could tell me if the focus is shared between the different cameras or independant?
