I want to remove
vat from checkout on run-time, If
vat number field has some value.
I am able to validate vat number on run-time on checkout (via this link Programmatically check VAT number is valid in checkout page magento 2.3.X? ) but didn't know how to remove vat from order total and shipping. Also I know Magento provides vat validation and removal from configuration but that only works for logged in customers.
