How to turn off the freezer of the Mijia Refrigerator Cross Door 510L?

The freezer of the Mijia Refrigerator Cross Door 510L can’t be turned off separately because of its single-cycle refrigeration system.
Here is more information about the single-cycle refrigeration system on the device for your reference:
1. A single-cycle refrigeration system in a fridge uses one compressor and one cooling circuit to cool both the refrigerator and freezer compartments;
2. Cold air is generated in the freezer section and then circulated to the fridge compartment. This design simplifies the system, making it more cost-effective and energy-efficient;
3. The freezer compartment on the system stores food at sub-zero temperatures, preserving it for longer periods.
