I believe only full duplex is supported when speed is set to 1000 mbps. Hence, it should already be doing auto-full duplex with 1000 speed. The following CCO link seems to suggest the same.

Note When the interface is set to 1000 Mbps, you cannot change the duplex mode from full duplex to half duplex.
