ADXL362 Power Enable via GPIO

I am powering the ADXL362 off of a GPIO at 2.8V. If this GPIO is pulled low and the CS is still held high it sinks ~30mA through the CS pin. Through software I have a power enable function that properly handles both IO, but I'd also like to prevent this in hardware. Would the best way be to put a current limiting resistor in line with CS? What about if the MOSI/MISO/CLK lines were held high? Trying to keep this application as low power as possible.
