I have to make the PO number as non required field using custom module and not in the theme level as we are running our website as a hybrid model. When I refer for solution, I am getting to make the po number as non required field in theme level. Example: How to make purchase order number optional in checkout page magento 2.3
I knew we can override the template using custom module but its not working. Can anyone please tell me the steps to make the PO optional that would be really helpful.
