How to bake directional light without realtime shadows?

I want to bake my directional lights shadows from the trees in my scene onto the terrain. Everything is tagged as static. But when I bake, I still have to set it to Baked Shadows: On (Realtime: Hard shadows) for it to show up.

I dont want realtime shadows though, I just want to bake the shadows onto the terrain.

In the light’s Lightmapping drop-down (at the bottom of the Light inspector, or the top of the Bake->Lights floating panel’s options), you can set your light to Baked Only.

You can also disable your light’s shadows at runtime, with

light.shadows = LightShadows.None;
