Remove all Discount references on Quote PDF until utilitized

Question:

How do I remove Discount references to Customer-facing Quote PDFs (not the worksheet), if Discounts aren't applied? Our Sales team would like Customers not receiving discounts, to see no reference about them.

Although I think it would seem to be a "visible if" calculation, I'm unsure which field/s and what formulas to apply - or if there was another solution someone has tried? We are using 10.0 | Enterprise | Sugar on-demand.

Thanks in advance for any ideas / solutions
