UPDATE (Successfully Done) - Reduce Credit Limit on ICICI Credit Card.

In imobile app, go to credit card --> Manage card --> Manage credit limit -->  you can reduce the credit limit to whatever limit you want

Thanks for the suggestions. But, the issue is you all must be knowing that there is a concept of maximum permissible credit limit which takes into account all the Loan accounts as well as Credit Cards. And, the over inflated Credit Limit provided by CC issuers eat into that, which results in lower probability of getting the desired Loan amount and issuance of new Credit Cards. So, that's why. Credit Limit provided by ICICI on my two Credit Cards is Rs.10L out of which I will hardly even touch 2L. That’s why I wanted to decrease the credit Limit.

Close credit card and get rid of it

Talk to the customer care and they will lower your assigned credit limit. I've seen someone done it in SBI last year.

I have done it via, netbanking -- View and Manage your Credit Cards --  Manage Credit Card Limits

and decrease it from there
