@purismforum, If you don’t mind, I would like to find out if we can detect the cameras.

Can you first install the following packages:
sudo apt install device-tree-compiler i2c-tools

Then, switch to root and save the terminal output to a text file:
sudo -s
script ~/findcameras.log

Now let’s see if we can find the cameras:
dmesg | grep -i camera
v4l2-ctl --list-devices
(I’m not sure if you are using video4linux but worth a shot)

i2cdetect -l
ls -l /dev/vid*

dtc -I fs -O dts -o ~/devtree.txt /sys/firmware/devicetree/base

If that doesn’t find the device tree files, then try this to find the device tree binary file:
find / -name "*.dtb"

If you find the .dtb file, then use this command:
dtc -I dtb -O dts -o ~/devtree.txt /path/to/x.dtb
(replace /path/to/x.dtb with the .dtb file that you found using the previous command)

Finally, try this:
find /proc/device-tree/ -type f -exec head {} + | less

Finally stop logging the output and exit as root:
exit
exit

When done, post the contents of your /root/findcameras.log and /root/devtree.txt files. Hopefully, we can find the camera.
