ISR 4451-x cannot set duplex or speed on SFP port

Been trying to set the speed and duplex on port G0/0/2 which is an sfp WAN connection.  I am unable to set it via command line as it says invalid input.  Also tried to set it via CCP but will not send commands and errors out on speed 1000 duplex full.  Only command I can get to go through is either negotiation auto or no negotiation auto.

 

interface GigabitEthernet0/0/2
 description To ATT Router$ES_LAN$$ETH-WAN$
 ip address x.x.x.x  x.x.x.x
 no ip redirects
 no ip proxy-arp
 ip access-group sdm_gigabitethernet0/2_in in
 media-type sfp
 no negotiation auto
 service-policy input CCP-QoS-Policy-1
 service-policy output CCP-QoS-Policy-2
end

CCGateway#config t
Enter configuration commands, one per line.  End with CNTL/Z.
CCGateway(config)#int g0/0/2
CCGateway(config-if)#speed 1000

If it is fiber port than duplex should already be set to full and speed of 1Gig.

That is what I was thinking as I have been going through this process.  Thanks for the response.
