What is the correct landscape import method for large worlds?

Hi,
I’m a little overwhelmed with the topic. What is the correct way to import a 8192x8192 meter landscape (I’ve got a 8192x8192 pixel heightmap) with the same number of pixel heightmap? I was googling and asking chatgpt but it was talking nonsense.

Should I import them in tiles or should I turn on World partition?

I have Gaea indie, but they used false advertising with the UE import bridge as its not compatible with 5.7.
