Decrease Ambient Occlusion Distance?

Hello, I've been working on a reshade preset for Dark Souls 2; Sotfs. I've been working on this preset for almost 2 years, continually trying to replicate the E3 lighting. After all this time, I'm actually very, very close to release. In fact, I consider the preset finished. There's just one issue. One of the effects I'm using is Raymarch ambient occlusion. It looks really nice. The issue is, it is extremely visible through distant fog, and it also weirdly shades distant sprite lod. I'm wondering how I would (if it's possible) decrease the ambient occlusion distance, making it only visible on things closer to the player character.
