You should be able to use NAT-0 with an access-list..
For example.
nat (inside) 0 access-list no-nat
nat (inside) 1 192.168.1.0 255.255.255.0 0 0
global (outside) 1 interface
access-list no-nat deny ip any host 192.168.1.1 (will be translated)
access-list no-nat permit ip any any (will NOT be translated).
