You can turn off the peak display entirely, but, this also hides the video frames as well. I'm not sure why these two things are tied to the same control checkbox.
On the other hand, i don't really understand why you wouldn't want to see them.

Specifically, when I import a single AV file for the sole reason of rendering its audio to a separate file. I then have to wait for Vegas to finish its peaks because it won’t let me render the audio until it is finished. And when I am done with the audio rendering, I have two unnecessary files in the directory of the original AV file, and I have to delete them.
