LTC4089-5 cost reduction

Hi,

We are doing some cost reduction studies for our product. On the power management circuitry we don't need the LTC4089-5 chip's high voltage input. All power is taken from USB Vbus voltage. 

 

So, if the high voltage input is not used can I safely remove all the components inside the red circles?
