if you are refering to what level of ChanOp has access to akick, this can be done on the access levels system, simply turn xop off: /chanserv set #channel xop off Then adjust akick to whatever level you are wishing 3 = voice, 4 = halfop, 5 = aop, 10 = sop, 10000 = founder.
If you are refering to making it so only sops can akick then a module can do that easy enough.
