I am not a IP Filter user and don't know the details of ipnat syntax,
but generally yes. Generally to exclude things from redirection one
inserts a rule prior to the redirection rule accepting the traffic
without redirection.

You might also be able to refine the redirection rule to say "redirect
anything but my servers".

See the ipnat documentation for your system.

At a quick glance at the ipnat documentation the following might work

  map ex0 from any to your.server.network/mask ->
your.server.network/mask
  rdr ex0 0/0 port 80 -> 192.168.0.1 port 3128 tcp
