Small, frequent patches of infinite ores

[AngledLuffa]

I added just the Angel's Infinite Ores to an existing map without RSO. I now get many small patches of infinite ores appearing in new territory I haven't explored in the past. Is there a way to reduce the frequency? I know I can just ignore any ore patches I don't want to use, but somehow that doesn't feel right. If I turn off the infinite ores now, all the existing patches are removed, so that isn't really an option.
