Cibil doesn't remove enquiries based on disputes afaik. It can only do it if HDFC approves or asks cibil to remove.
The only option is to ask the bank to suppress the enquiry. HDFC is a nighmare in this regard. It took 3 months for them to accept that they'll remove the enquiry, they kept ignoring and dodging my mails.
If you have the patience, give it a try.
