We have requirement to restrict the user from selecting the Remit to bank account while creating Inv

Presently, we have the supplier bank accounts configured at site level and we have requirement to restrict the user from changing the supplier bank account which gets defaulted from site level. We tried to uncheck "Allow override of supplier site bank account" under Manage Payment options page. But it is not working, and the account selection is not getting restricted.

Has anyone come across any such requirement? What was the solution provided?
