Water plugin tool vram hungry


I created landscape and drag and drop water body ocean on landscape . The problem is it uses so much vram and if i use more water content i am going to run out of vram even without shape my world that i created. i have 7900 xt and it has 20gb vram. Is this some kind of bug that it happens or do i need do something to fix it. I also added images about my problem above.
