Culling Methods Usage

Hello there!
Searching around for optimization methods i’ve come to know that there’s a bunch of things called “culling methods”, but the thing i can’t understand is: are all basically automated?
I know that LoD management, cull volumes and level streaming need some setup, but i can’t find anything about how to setup dynamic occlusion and camera frustum culling, it seems like it’s entirely automated and that’s all…but i need to understand if this is true or not and/or if there’s a way to manipulate the outcomes for those culling methods or, at least, if i can test to see properly how they work.
I’ve already seen some livestream on the youtube channel, but they just explain what culling methods are and how they work and not how to setup them.
Anyone can help me providing some infos about their usage?
