Turn off Freezer in Beko RRN 1671

[Bnecarara]

Hi,

I have a Beko RRN 1671 fridge with built in freezer compartment.
I have recently bought a bigger stand-alone freezer, so I don't really need the freezer compartment in my fridge. So, might as well try to turn it off to save some power.

How do I do this?

I've taken a look at the thermostat inside, but I'm not really sure if it will turn off if I pull out one off the clips with wires attached to the thermostat element.
There is one black, one blue, one yellow-geen and one brown wire.

Anybody have any ideas?

thx

This is how the thermostat looks like:
