HighRes Rendering 10-16K issue

Hi all! I did not see similar topics and the Internet did not give me an answer. I have an RTX 2080 , I’m trying to render a 16K image with a Movie Render Queue with tile 10. I’ve seen quite a few videos where people with GTX 1050Ti did it easily and without errors. I constantly get an error about insufficient video memory. I don’t know what I need to do to render with this function. Also one more question, in my scene there is MetaHuman do I need to select “Override SubScattering”? Thanks
