Hello everyone, this might be a dumb question but here goes, I mailed my I-130 over a month ago and still no word

anyway in the cover letter i wrote that the petition is for a K3 visa, but now we are wanted to go the IR visa route what do i do? is it as simple as not filing the I-129f after NOA1? or is there something else i have to do? will the I-130 be processed as a IR visa petition?
