Turn off "life gate will open as long as the key fob is near" function?

On my April 2020-manufactured last-of-the MkIII Facelift (2017-2019) Octavia Scout (combi/wagon/estate, diesel, 4x4, DSG-7, 135kW/184cv, suspension about 3cm higher than the standard combi/wagon/estate model), the rear lift gate will always open, no matter the door lock status, if I have a key fob near the rear lift gate and I press the exterior rear lift gate button.

Is there a way to set it so that the rear lift gate will only open if the driver's door (or, any front door) is already unlocked?

I found some discussion of the Car Opening & Closing settings, and I tried setting it to One Door Only, but it made no difference.

thanks,
