You can repay in advance.

Two aspects need to be noted:

1. You need to contact the bank’s customer service in advance to terminate the installment. If you do not apply for termination, the remaining balance in the installment will not be billed at once, but will still occupy the card balance.

2. Even if the installment is ended early, the remaining installment fees will still be charged. In order to avoid this situation, the installment payment must be canceled first and then repaid, so that each installment will not be charged again. There is a handling fee.
