Hi Satyam,

I hope you are doing good. Now Coming to your query, As per my research, After getting a seat in any round, if you want to accept the seat then you have top report RC   which means to change the option from Float to Freeze you have to go to Reporting Centre that to before due date otherwise your seat will be canceled and given to some other student in Special Round.

I hope this helps.

All the best.

Thank you.
