I hope not. Most of the security for modbus are in the form of MasterLocks (those locks everyone learning to pick lock buy a dozen of). If you have physical access to the system it's assumed you're supposed to be there.
At least in the limited number of systems I've seen, modbus is used for communicating status rather than control.
