Best way to batch edit for background blur

I have about 600 photos from a trip I just took. Many of them were portraits that have a background blur effect that looked kind of cool at time time, but is in most cases fairly buggy or needs to be readjusted. I would like to remove the background blur effect on all my photos at once. Is there a good way to batch edit these? Guides I've seen suggest I can just multi-select and chose "edit" but there is no option to edit anything other than location or date. Is this going to require a third party app or is there a way to do this with the gallery app? I have seen that lightroom or snapseed can sort of do this, but I'm not sure if they will remove samsung's background blur or just be able to add/remove their own. Anyone have a quick fix?

EDIT: I have fixed it manually, but if anyone does know of a batch editing method, feel free to comment for posterity in case someone else needs this info. Cheers!
