How to disable crossfire in HD 7990?

Can anyone explain me how do I disable crossfire in the HD 7990? I am using 13.9 drivers, and in CCC there is no option to disable it. In the (Gaming / 3D Apllication settings / AMD CrossfireX) there is only an option to turn frame pacing on or off, but no 'disable crossfire' option. Also, in RadeonPro I can't seem to find an option to disable it too, and i'm kinda tired of not being able to play games like War Thunder because of that.

    You cannot disable crossfire in the HD 7990, as the two chips are hardwired into CrossfireX.
