The “minecraft” trees are baked into photogrammetry and as far as I’m aware can only be removed by hand. Blackshark have been working on an AI solution but I suspect the problem is recreating believable results for whatever textures the trees would originally have been hiding e.g. up against buildings or overhanging of streets etc.
It seems to affect older PG the worst and I believe this will be cured by current and future capturing methods that include the use of AI and possibly seasonal comparisons.
