Unreal 5.4 Builds are taking long. Possible DDC issue.

Our team recently moved our project from 5.3.2 to 5.4.2 and builds are taking really long. We didn’t do a full migration, just an engine switch. We don’t use networked DDC or anything like that - but since we moved to 5.4.2 it seems like every single shader is compiled on every build and it isn’t using the local cache on build machines at all. Is there anything we can pass into BuildCookRun that will force it to use the cache or at least pass compiled shaders into the cache if missing?

Also is there some .ini or settings file that could have been changed that handles this?

Thanks.
