All the Indian men from India I’ve seen who did well with women living in the West just kept their accents and didn’t worry about it. There are accent reduction classes you can take that aim to train you to speak like a local wherever you are, but I don’t see much point if the only goal is to do better with girls.
Think of it like this: if you have tight fundamentals and a solid skill set and process with women, your accent only adds to the charm. Even if you have an accent from a usually-less-desired background, when you walk up brimming with charm and confidence it’s taken as an extra plus, because you aren’t supposed to be cool and sexy, so… you must really have something going on.
I’d not worry about the accent. Just own it / ignore it, and focus on the stuff that matters (fundamentals + game).
