No need to do anything in website, you are already eligible for CSAB 2nd Round.
Below is the rule-
Those candidates who have not been allotted any seat at the end of Special Round-I, and NOT EXERCISING the option of NOT WILLING TO PARTICIPATE IN THE SPECIAL ROUND – II shall be considered for the Special Round-II.
