This is the "Active AF Sensor" aka 0xd108 property.

For my D7000 it has values from 1-39.

        gphoto2 --get-config d108
        gphoto2 --set-config d108=XX

We are so far not encoding/decoding it further, but this could be done.

You probably need to change the Focus Metering mode to Single Area too.

        gphoto2 --get-config focusmode
        gphoto2 --set-config focusmode=AF-S
