Hi Srivardhan,
I hope you are doing good. Now Coming to your query, If you want to participate in the 2nd round of counseling then you can cancel/reject the seat before the due date by visiting RC/Institution. If you don't cancel it before the due date then they consider that you accepted the seat and then you are not eligible to participate in any further rounds.
I hope this helps.
All the best.
Thank you.
