EBT: Tax on Receivables Transaction (Invoice) based on Transaction Type

Hello, I have a bunch of Transaction Types that we use in Receivables, but only 3 of them should generate tax lines.  However, since I setup the tax to be Applicable by default, everything is being taxed.   How can I setup EBT for Receivables so that the tax code is not applicable unless A/R transaction contains one of the transaction types that I've determined should be taxable?

My preference would be to enable a DFF on the Transaction Type and if this attribute is N, then that transaction should not be taxable, but I am not sure if that is possible.
