It can be enabled in the Project Settings (`rendering/quality/filters/use_debanding`). It's disabled by default as it has a small performance impact and can make PNG screenshots much larger (due to how dithering works). As a result, it should be enabled only when banding is noticeable enough. Since debanding requires a HDR viewport to work, it's only supported in the GLES3 backend.
