Western classical and Indian classical violin are very, very different styles. The main similarity is that they use the same instrument, so if you learned one style, you would have a head start learning the other.
For either style, you will need to be familiar with your instrument and learn where to find notes, and how to control the bow.
There are a lot more differences than similarities.
How the instrument is held: In western music, the instrument is held at your neck, and is played either standing or seated in a chair. In Indian classical, it is usually played seated on the floor, with the instrument upright and the bottom of the instrument's body supported by the ground. It would be very, very difficult to switch between these for someone who hasn't extensively practiced both positions.
Both styles use rhythm and pitch as the core of making music, but the details are profoundly different.
There are differences in how the styles use scales, whether and how they use harmonies, what notes are considered notes, the use of improvisation, in how rhythm is used, and more. These differences are at such a basic level that even a beginner's very first lessons will be very different between the styles.
I play western violin, but took a workshop in Indian Classical once. The differences in the music were huge, and I struggled to frame even the basics in my musical understanding. If you know you want to play western music, I'd start by learning that, rather than learning Indian, then changing styles.
If you can't find a teacher, I'd suggest using looking for a teacher who will teach over the internet, and in the mean time using internet video lessons. ProfessorV on YouTube is a good place to start.
