Is there an option in the ACC module for this, or I should handle dialog tracking using dialog module?
No, there's no option for it in the ACC module.
Using dialog tracking is one option. Adding a database constraint or trigger that would prevent it is another; that's my preferred approach.
The ACC module is stateless. Think of it as a relatively unintelligent logger. As with all loggers, it's your choice what to log, and to devise means by which to prevent certain things from being logged.
