Full-duplex on EWAN interface

When running the WAN interface in dual mode, with EWAN as the primary connection and ADSL as the backup, is it possible to set the EWAN interface to run in full-duplex?
I can't see an option in the web gui, and the CLI doesn't seem to have any explicit mention of duplex modes either.
The third-party we're getting the WAN connection from requires us to run the ewan interface in full-duplex mode...
7800N running firmware 1.06g

The EWAN port on the 7800 series can only run at 100Mbps max, this is a hardware limitation

The ewan connection is only 10Mpbs; are you saying that the WAN port can only do half-duplex?

OK, so after telneting and running a shell, you can configure the WAN (eth0) with:
ethctl eth0 media-type 10FD (for 10Mb full duplex)
or
ethctl eth0 media-type 100FD (for 100Mb full duplex)
set back to auto-sensing with ethctl eth0 media-type auto

On all vEdge router models, all interfaces support 1-Gigabit Ethernet SFPs. These SFPs can either be copper or fiber. For fiber SFPs, the supported speeds are 1 Gbps full duplex and 100 Mbps full duplex. For copper SFPs, the supported speeds are 10/100/1000 Mbps and half/full duplex. By default, the router autonegotiates the speed and duplex values for the interfaces.
