We are investigating a way to update the fields ‘Allow tax applicability’ and ‘Allow offset taxes’

There are these two documents which were found online but are not helpful in our case:

PRC: POZ: Unable to Update "Allow Tax Applicability" At Supplier Address Level using REST API (Doc ID 2834136.1)

How to Upload Tax Classification Code, Allow Tax Applicability, Allow Offset Taxes (Doc ID 2247576.1)

The fields must not be updated neither manually nor by spreadsheet and we must be able to mass update if possible.
