I in an earlier post asking about fixing the plastic cable guide under the BB shell offered a drilled hole, with a pop rivet..
once the pop rivet is fixed, the inner end expanded, the pin that does that breaks off, in the jaws of the pop rivet setting tool,
and the ball on the end that is doing the expanding, can fall out, once it is done,
both securing the cable guide, and leaving a hole in the center of the pop rivet.. your drain..
worried about 'voiding the frame warranty' have the dealer that you bought the bike from, do the work.
