Can the time parameters of a Simulink modell be changed after it is with Simulink Coder compiled?

I have a Simulink modell which I call from a Matlab application and its Time Parameters are changed many times during the application, what I want to know is, if I can change these Parameters once I compile the Modell with Simulink Coder, and how would I do so?

Thank you in advance

It's not clear what you mean by "Time Parameters"? If you mean sample-times, I don't think that is possible, but it you are referring to tunable parameters of blocks, it should be possible.
