If the custom board design uses USB Type-C connector, the USBn_ID signals are not required to be connected. The DRD mode switching is controlled by the USB Type-C companion device.
DRP (Dual Role Port) requires a controller, primarily to switch power based on the negotiated role. In a Device Mode only, USB2.0 only, Type-C implementations where the device is not powered by the Type-C connector, no Type-C controller is required.
Also ensure you follow the USBn_VBUS input scaling recommendations. Refer the section USB VBUS Design Guidelines of the device-specific data sheet for more details.
The AM62 SK USB0 interface design can be used as a reference for implementation of USB Type-C interface.
