64MP Quad-Camera independant focus?

Hi,

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?

Thank you for your help
