It's currently among the highest voted-for mods on Nexus Mods (via PCGamer), with over 15,000 downloads so far. Doing this means you'll miss on the 100 free, introductory credits Bethesda offers, but if you really hate it that much, that's not really a loss. Created by InAComaDial999, the mod has a single job: remove the Creation Club box from the top right corner of the main menu screen. No More Creation Club News is a simple mod for the PC version. Fear not, though, because mods always find a solution. This particular addition came with the game's most recent update, which launched alongside Creation Club.
Unless of course you really hate having to see the Creation Club news box every time you launch Fallout 4. Still, you can mostly ignore it and play your Fallout 4 without issue. Bethesda's recent launch of the Creation Club mod market didn't exactly go well with the fans.
