How can we make bank account as mandatory field in Invoice Installments section in ACH method

We have a requirement where we want bank account as mandatory field in Invoice Installments section.

We tried adding Validation Holds in Manage Payment Method but drawback is here that invoice is still getting validated and also the hold created is releasable.

Is there any way where we can make bank account as mandatory field or somehow this hold created becomes non-releasable.

Thanks
