nRF9160 Modem Firmware v1.0.0: Setting custom DNS server

Hello,

The release-notes of the Modem Firmware v1.0.0 for the nRF9160 state that there is now "Support for DNS server address setting by application.". However, I cannot find how to actually use this feature anywhere.

Is there perhaps an AT-command that is not documented yet? I'm looking at the AT Command Reference v1.0.

Can someone please help me out?
