Is it possible to completely power off usb ports from system?

    No, unfortunately not.

    Since this board is so similar to the Raspberry Pi and since Intel has not released a schematic, this answer is based off of the Raspberry Pi forum. The USB port is physically attached the board's power supply and therefore cannot be turned off.

    This can be tested by shutting down the system using the sudo shutdown now command. Notice, that even though the system is powered down, all devices (including the cooling fan) remain powered. However, if you place a transistor inline on the power line you can use the GPIO pins to toggle power states but this will require a breakout board/custom hat.

    Good luck!
