As I  understand it, the  module you want  to disable is  being selected
(for build)  because of the boolean  logic shown here. If  you have CNIC
*and* NETDEVICES  *and* ETHERNET *and*  ... (and  so on), then  you must
also have the Broadcom QLogic NetXtreme II driver.

Now, a quick  check on the first  of those (I searched  the internet for
'linux kernel  CNIC', no quotes  and took the  first link) shows  me [1]
that the CNIC driver "supports offload features of Broadcom NetXtreme II
gigabit Ethernet cards".

So, at the moment, you're trying to build the offloading driver for that
card as  a module  ("CNIC=m") but not  the main driver  for the  card. I
doubt that's going to work.

I would suggest saying no to CNIC and you should then be able to disable
the other driver.
