A console & INI file unlocker has been posted to hxxps://www.nexusmods.com/finalfantasy7remake/mods/74 (can't post link for some reason)
(apparently the game had some issues with console which is why UUU didn't work for it, but the unlocker linked above should work around them)
Also allows game to read from standard UE4 INI files like Engine.ini, so cvars can be changed without needing to pak them first.
Would be nice to add this in the article, not sure what the best section for it is though.
