There's a certain line you need to draw when considering unknown unknowns. You're suggesting that changing surface features on a remote body in space could somehow affect Earth. Consider that the moon has been hit by very large asteroids in the past which caused disruption on a scale beyond what we could ever do and we don't have any indication that it has affected the Earth other than kicking up some meteor showers. Worrying that we could somehow provoke something more is akin to worrying that driving to the grocery store will trigger an ecological collapse. We have no reason to think it will, we can't even posit something that sounds plausible, but there could be unknown unknowns that make it so.
