    Do I need to add pull-up resistor for CS and ACK pin and pull-low resistor for other SPI pins to reduce the leakage current?

    It is not needed to add the pull low or pull high resistors for the SPI pins. Attention should be pay to set the input/output pins correctly or else leakage will happen.
