Convert to PDF without producing a cover

Hi,
as the title says , I want to convert to pdf, but NOT produce any cover.
I am converting to PDF for Amazon KDP paperback. Converting to PDF works very well. HOWEVER, it leaves me with a cover page, which I do not want.
How do I convert WITHOUT producing a cover page ?
( As you no doubt know, Amazon requires a separate PDF for paperback covers anyway ).

thanks in advance,
