Can you disable the requirement to add bank account details in the Request New Supplier process

Summary:

The business currently has a process whereby a request for a new supplier is submitted. the bank account details are added as a final step once the supplier has been approved by the Procurement Team.

They wish to utilise the RSSP process of Requesting a New Supplier but would like to have the bank account details added after the submission and approval of the supplier. Currently the RSSP process makes adding a bank account compulsory.

As the Request for a New Supplier is a Pop up, can VBS be utilised to disable the Bank Account details requirement or any other suggestion please.
