Macbook wallpaper take up a lot of space, cannot get rid of them.

This folder have is >20 video of scenery, which I dont think i see them before. I think it is the dynamic wallpaper, and i never used it so IDK why it would automatically download it, also it is these video is taking up about 42GB, which i dont have much space left. It will automatically download it again after i delete it, and I really want to stop download it. Now I am delete it once a few day and it seem like it is downloading at night??? I never used it and there is no reason it is downloading it automatically, so i wonder how I can disable the downloading of these wallpaper, well if there are any terminal command that can stop it i will be very happy. cannot stop downloading it in the settings. Also I am using my own wallpaper, the pic I take by myself, so it should not be related to those wallpaper. BTW, I am using macbook pro m2 Chip with sequoia 15.0.1, the directory is at '/Library/Application Support/com.apple.idleassetsd/Customer/4KSDR240FPS' if you dont know where it is.
