Nautilus doesn't have this as a setting. When setting an image as background i get the error
Failed to set wallpaper via portal: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Wallpaper” on object at path /org/freedesktop/portal/desktop.
I also have a bash script which can set wallpapers and am using hyprland.
