How to turn off auto save?

Hi, I am new to reshade, using it for FFXIV. I like being able to tweak with presets that I already have; but I always want to have the original. Is there any way to not have any changes that I make auto save with every change? I sometimes mess up the entire preset and I don't know how to go back to it without having to redownload from the creators site. 
 

Uncheck Settings > Overlay & Styling > Save current preset automatically on every modification. A new button will then appear next to the save and plus buttons at the top right of the Home page (with a rotating arrow symbol), which when clicked will undo all modifications done since the preset was last saved (which now only happens when clicking the save button next to it).

Going to try this out now. Thank you so much for your response!

Update: Got it! Thank you so very much! Truly have saved me so much time and headache!!!

I also managed to turn it off. Lucky to have found your post.
