Any options to turnoff Acquisition Cost Adjustments raised from Invoice Tax rate variances?

Summary:

The customer uses a third-party system 'Vertex', for tax calculations on payables invoices and there are no tax estimates or calculations at the purchase order level. According to Oracle documentation, we understand that system treats this as a tax rate variance due to differences in taxes between the purchase order and the invoice. These variances are then passed to cost and receipt accounting as acquisition cost adjustments.

We are also aware of the profile option "Ignore Invoice Variances for Inventory Destination Purchase Orders" (ORA_CMR_IGNORE_AP_INV_VAR_ALL), which prevents passing invoice variances to item cost as acquisition cost adjustments.
