How to globally disable UE4 caching feature?

I built a new system for UE4 to ease working with the editor. It’s quite powerful for light and shaders calculations but its weak point is the 128GB SSD. I want to save space and extend its lifetime so I wonder whether it is possible to turn off all the caching features for all my current and future projects at once? I don’t need light or shaders to be cached since its calculating is fast enough.
