Poor dynamic shadows quality of stationary light

Hi! According to official documentation Unreal stationary light source can cast dynamic shadows for movable object like Movable light. But it has too poor shadows quality. Really stationary light have twice lower quality then movable light (mesh with scale 1 in case of stationary light has such shadow as mesh with scale 0.5 and movable light).

Look to this image, equal objects here, with equal settings. Only difference is the Stationary or Movable light mobility.

In the past it was possible to increase shadow quality by scalability settings. But since version 14 there are no control (default settings are maximum), and as the result no possibility to show shadows for small objects.

Is there still some way to fix it and achieve shadows quality for stationary light like movable light (for movable meshes)?
