How to create landscape larger than 8129 x 8129(overall size) with world partition, for open-world game?

So if I understand correctly, if I create heightmaps somewhere outside of UE5 and I need to create a massive openworld and don’t want to spend all memory in the world on one giant landscape I can split my world to a number of moderate size landscapes My PC can handle and still use world partition on each of them as well as for the whole world?
