The biopic on the "Munnabhai MBBS" star is being helmed by Rajkumar Hirani.
Gossip mills are abuzz that the 33-year-old-actor is being trained under Dutt.
Dismissing such reports, Dutt said, "As of now there is no training or tips that I have given to Ranbir (Kapoor). I am not giving him any training for the film. Raju (Rajkumar Hirani) is there so he will take care of everything properly."
The 57-year-old actor was released in February after serving his sentence in the 1993 Mumbai blasts case.
