Outriders (UE4) jittery shadows

hello
i have jittery shadow on the outriders. i tried many settings(low-ultra shadows dx11-dx12 TAA-FXAA-OFF) but still same issue. i remember seeing these annoying shadows in "COD modern warfare remastered" too. it seems a method for soft shadows etc or maybe its AO issue idk properly. i prefer hard shadow myself ( also i guess hard shadow have better performance).also i noticed my character have better shadow. can someone help me get rid of it? i think there should be a way to adjust the shadows better in the UE4 settings.
sry for my bad eng

thanks. can i turn it off?

 

No, its the way they are doing environment shadows without using a soft blur on them to hide it.

 

Have yout ried using Temporal AA.
