Yup. You should place them inside the Mods folder under \Documents\Larian Studios\Divinity Original Sin 2 Definitive Edition\, then you handle the rest from the mods menu ingame. Most mods are fine regardless of load order, except for those who has a core mod they depend on, or otherwise specify where they should be in a load order. So just keep an eye out for details about that in mod descriptions.
If nothing is mentioned, it's likely no relevance where in the load order they are
