Want to delete a single mod from a modpack I'm playing

Hi, I've been running Another Quality Modpack 2 [Fabric] on my server. The problem we've been getting is that every time the modpack updates the internal terralith seed changes and causes really unappealing chunk errors to occur with biomes half generating. We wanted to complete remove terralith to fix this issue but I noticed I no longer have access to the mod folder. I just want to delete a single mod, I don't want to upload anything into the folder. I appreciate any help.
