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.

From CCO

""Setting the Interface Duplex Mode

--------------------------------------------------------------------------------

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