Disable Unofficial Plugins?

I've tried editing the .ini file to disable the unofficial plugins and the provided line:

AllowUnofficial = 0

That's not doing the trick. I'm just trying to disable the additional ported weapons. I'm looking for an experience as close to vanilla as possible. I've also tried temporarily deleting several different files from within the directory, then putting them back if it didn't work. Nothing's getting rid of them.

Any help is appreciated. Thanks.
