There is no way to directly handle the installment payment. Your available balance is insufficient. The installment amount occupies the credit limit of the card. You can raise the temporary limit first, or you can deposit before spending, and then you can pay by installments.

You can call the customer service to adjust the temporary quota, and then explain to the customer service what the value of your purchase is, how to pay in installments and how much you have to pay each month. Customer service will tell you.
