I’m not 100% about whether or not this gets rid of it completely, but it should remove it from the game. Pretty sure you have to go to the ‘Installations’ tab, then go down to Forge (whatever version you have), then click the three dots to open up the drop-down menu, and from there you can click ‘Delete’. I’ve seen videos on how to remove an old version of Forge completely (which involves going to the roaming section of Minecraft, going to versions, and then deleting the old Forge version), but then got stuck on the part where you have to delete the old Forge on the launcher. I then started to notice that one or two mods (or more) required a higher version of Forge (the one that I wanted to install was version 1.16.5- 36.0.48). Recently I have installed Minecraft Forge MC 1.16.5 and wanted to download a couple of mods for Minecraft 1.16.5.
