Inside your GTA Sa Folder, if you have s0beit installed there should be a folder called " mod_sa "
Open that folder, and inside that folder should be a file called "mod_sa" as well and should look like this

After you open that file, you should make your own search and see where are the options of s0beit. In order to make it easier for you, maybe take a screenshot of your s0beit in-game and have that screenshot open, so you can find what you look for.
For example, I have YPS project, and there's some options I could edit

I hope I helped
