The loan installment has nothing to do with learning or not, and it needs to be repaid on time after the loan. If you don't want to learn, you need to consult a school, not a lending institution.
Most of these loans are cooperative relationships with educational institutions. The money has been lent out and can only be repaid normally or in advance. If you don't want to study, you can only negotiate whether you can refund part of your tuition. The loan should be paid on time and cannot be overdue.
