Given how previous Bethesda games have worked you’ll get basic mods like texture replacers and the like for the first few days/weeks until modders figure out some of the differences between FO4’s plugins and archives and Starfields then you’ll see some more substantial but still basic mods using tools like xEdit until Bethesda releases the creation kit a few months down the line and people can make larger more substantial mods like you see for Skyrim. One prominent modder plans on having dlss modded in I think by release since you’ll be able to get it early.
