The VBUS power is sourced by an external host. USB standard for device operation recommends connecting < 10 μF capacitor to the VBUS close to the USB type B connector.
Follow the USB VBUS Design Guidelines section of the device-specific data sheet to scale the USB VBUS voltage (supply near the USB interface connector) before connecting to USB0_VBUS pin.
Based on the use case, the zener diode can be removed if one is absolutely sure that the board will never experience a VBUS signal potential greater than 5.5 V (sourced on-board).
It is recommended to leave the USB0_ID pin floating.
