DFAO artefacts in shadows caused by movable SkyLight

Hi I have a video that shows the black artefacts (splotches) appear in shadows and that it’s caused by SkyLight’s cast shadows option. And that the SkyLight is probably using distance field AO to produce those shadows. I am using full dynamic lighting, GI is set to None in UE 5.4. Is there a way to tweak the DFAO or the skylight somehow to remove the black artefacts cuz they are way too visible? Or at least to minimize them because they are showing up in interiors as well? Turning off the “Cast Shadows” in SkyLight or DFAO completely is not an option because I need the interior shadows and darker areas. Especially because I will have an overcast lighting scenario where all of the scene will be in shadows
