In order to reduce the current consumption to the other devices connected with VDD_nRF power supply, VDD pin is needed to shut down the power (zero voltage level). In this case, can VDD pin be set zero voltage level in system ON mode?

The nRF52 chip itself is powered by the output of REG0, VDD. So if VDD was 0 volt the nRF52 would have been completely shut down as well. So it's not possible.
