Distance Field Shadows with MSAA

For a VR project, I’m using the forward renderer with MSAA. I’m trying to use a combination of cascaded shadow maps with distance field shadows for long-distance shadow as described in Distance Field Soft Shadows in Unreal Engine | Unreal Engine 5.0 Documentation

The distance field shadows have extreme aliasing when far away, to the point where it’s extremely distracting. But they look great up-close (I forced cascade shadows off to test).

I think temporal AA usually solves this problem, is there any way to fix it when using MSAA?
