Set VDD in firmware on nRF5340 DK

Set VDD in firmware on nRF5340 DKhttps://test-devzone.nordicsemi.com/f/nordic-q-a/88750/set-vdd-in-firmware-on-nrf5340-dkHi, The manual for nRF5340 DK states: "VDD can be set by the nRF5340 firmware". I need to set the VDD to 1.8V. How is this done? I can't find any code documentation on this.
