Making DFFs mandatory on the Supplier Registration Screen based on the Tax Country selected

Summary:

Hello,

We have a DFF on external supplier registration screen. By using Sandbox/Page Composer, is it possible to make this DFF mandatory based on the Tax Country selected?

For example, if the Tax Country is Israel, China, or Egypt, the customer wants to capture the local supplier name with the local letters in the Local Name DFF during the external supplier registration as it's not possible to use the Alternate Name field.

Thanks.

Regards,
