Do I see external threads on the freehub rotor? If so, you might well have the 600EX based UG/HG hybrid, in which case there will be no splines between the freehub stator and the hub shell, and you will need a TL-FH10 to take it apart. Tri spokes made by Specialized have this hub too, HED briefly used a normal HG hub before switching to their own hub design.
Once you have the axle out, there will either be a spline to fit tool TL-FH10 or a 10mm hex for a big Allen key on the hollow bolt identified as 11 in the diagram. The former means don't bother, you are not going to be able to use a Fixxer, the 10mm Allen key means it's a common splined freehub stator and you can go ahead with dismantling, make sure there isn't some weird third way I've never heard of, and then buy a Fixxer or the cheaper domestically produced SPNK clone
