See, Indian Institute of Information Technology Bangalore is a private institution and does not support any kind of reservation or quota and the admissions are there are completely on the basis of merit, without any consideration to gender, cast etc.

Unfortunately, the CSE at IIIT Bangalore in 2021 closed at 5500 rank in JEE Main, and with your percentile you won't get an admission there, but you can always try a second time and emerge victorious. All the best for your future preparation.
