How to disable Scan response

Hello we want to save power and there we had the idea to not send the scan response to the central. Because we don't need this exta 31 Byte for advertising data.

We use SDK 16 with Softdevice "s132_nrf52_7.0.1_softdevice".

I was able to don't set the scan response data but then we still have a scan response with empty data.

What must i chnage to disbale the scan resonse?
