Two soundtracks, your choice
Dual Audio was on the original menu because many people want Hollywood and South Indian films in Hindi. On Netflix, Prime Video and JioHotstar in India, a large share of those films come with a Hindi soundtrack beside the original.
Switching
Play the film, tap the screen, and open the Audio and Subtitles menu. Choose Hindi and the film continues in Hindi. On a TV remote, press down during playback to reach the same menu.
Good examples
Avengers: Endgame, Spider-Man: Brand New Day, RRR, Kalki 2898-AD and Pushpa 2 - The Rule usually carry Hindi audio in India.
