According to Razib Khan, endogomy is relatively rare in Bangladesh unlike the rest of South Asia. Most Bangladeshis have similar genetics, as in there is a lot of cross community marriages in the region.
India alone has about the same population as Europe, North Africa, and the Middle East combined. In my experience, the level of religious and cultural diversity is not dissimilar either. One should always be very careful in applying generalizations to the entire region.
That being said, David Reich has a good chapter on the deep history of very high levels of engogamy in India in his book "who we are and his we got here".

Wonderful read as always! Rare diseases unfortunately remain neglected in India and so does the scientific know how of how to avoid them. Wrote a piece on it a while back and thought of sharing it here: https://genomeofindia.substack.com/p/genome-10-udgam-of-india-a-genetic
I don’t think one should generalise too much from Pakistani samples to the rest of South Asia.
Brit Pakistanis have high rates of consanguinity. However, much of North India has strict anti-consanguinity taboos due to the ‘gotra’ system.
Might be different for parts of South India.
