While using the NITA scheme in transient simulations, is there a way to improve the convergence in each time step by increasing the inner iterations.

I mean is it possible at all to access the inner iterations control for NITA scheme

The question is not well posed. As NITA stands for "Non Iterative Time Advancement", you actually have only the inner iterations while the outer are missing. All your controls for the NITA are on inner iterations and relative Multigrid settings.
