Impact when Determine Tax Applicability" has Not Applicable as Default

If I setup E-Business Tax and set the “Determine Tax Applicability” default tax rule as “Not Applicable”, will that allow users to select when and where the associated tax regime, status, and tax?  They want to manually select (control) tax applied to invoice lines in Payables.

 

I’ve gone through the detailed setups of configuring E-Business Tax for Canada (with province jurisdictions, etc.).  However, the client insists on a ‘simple’ setup that will allow them to select the regime, status, tax, etc on AP Transactions.  The client has a separate tax regime for Receivables and are using Vertex.  Vertex created rules that not send tax lines to AP.  They have approximately 100 AP invoices per year and want to keep the process simple.
