No VAT Tax for Intercompany Inventory Transactions

Hi Gurus, I am new to tax module (& SFO !!). We have business scenario where I need your help

We are using SFO (Supply chain Financial Orchestration), now it seems like there are no setups in the SFO end to control which Tax code gets defaulted on the PO/SO that would created relating to Intercompany Inventory transactions

Scenario: There is an IC Transaction originated from SFO, across two LEs, which needs to be tagged as No VAT.

My Q's are

a. How to default such Tax Classification code on such IC transactions

b. Can this be part of User defined Fiscal Classifications ? I am attaching the screesnhot of the page from SFO, where we are expecting this tax code
