That's a very interesting idea.

I don't think splitting would do the job. Any chance that the noise regions
reported by the vamp plugin could turn into selected regions in Audacity? So
that one can edit them, for example to ignore a false positive, before silencing
all remaining regions at once?

What about vamp and ardour? Any other hosts for vamp plugins?
