Disable Control Amount in Invoice Header Tax tab

We have an ongoing issue with imported invoices from an integration where, ever since 24A, we are getting a lot of invoices with the "Tax amount range" hold.

Having raised an SR, we have been told the issue is the Control Amount field in the tax section of the invoice header. This seems to be populating from the integration invoices but we don't know how.

Can we disable this field altogether and what would be the impact of this as the invoice lines have the tax from the integration anyway as well as the PO.
