I had this exact same issue on one of my machines, and I found out that the "openib" (InfiniBand) package was installed and enabled, although not needed. The InfiniBand modules were loading the ipv6 module as a dependency, that way it was being indirectly activated. After uninstalling the RPM and rebooting the machine, it no longer has IPv6 active. If that is not the specific case with you, see in the output of "lsmod" if ipv6 is being used by another module, if that is the case, you can try to see who is pulling that module and try to desactivate that one.
