Correct way to uninstall dlc/updates?

[GoKirbyGo]

Hi, what is the correct way to uninstall dlc/updates on SX OS 2.5.2 and FW 6.2.0?
I googled and realized that I needed to use DevMenu, but I can't find DevMenu for 6.2.0.

Never used the dev menu myself, but you can use the SX Installer. In my opinion best option is to back up your save file just in case and then just delete the game and reinstall just the base game.
