… Do all Fallout 4 mods disable achievements? Saber Interactive says that “subscribing will automatically start a download, and once it’s done, you can select and activate each mod you want available when you launch the game.” We haven’t been able to confirm if downloading and enabling mods disables PlayStation trophies. Enabling sandbox mode or debug mode disables Steam achievements.

Using mods does not disable Steam achievements. Achievements are blocked no matter what kind of mod you activate.
