This option is available only in UltraScale and UltraScale+ devices. When enabled, it generates the Aurora core without the GT and moves the transceiver from the core to the support level in example design. Table: List of Ports to Interact with GT Transceiver provides the list of ports used to interact with the GT transceiver, outside the Aurora IP.
