How to remove the bank card bound by installment?

If you choose to pay by installments, usually after the application is successful, the number of installments applied for cannot be changed or cancelled. Even if the bank allows you to repay in advance, the fees collected will not be refunded, and you will be asked to collect the fees that have not been collected. That is to say, you have to pay in advance, and you won't save any money. After installment payment, it will occupy your credit line.
