Day night cycle in URP with two directional lights

I have a pretty simple set up for a day night cycle in my game following this tutorial

and I wanted to add a separate directional light to represent the moon, which I simply added as a child of the existing directional light so it rotated at the same speed and everything.

The problem with this is that only one of the lights can cast shadows at a time, and I have found no documentation on this, except a post complaining about the same issue from 3 years ago. This doesn’t seem like that complicated of a thing to add, but I cannot for the life of me figure this out.

Any help would be greatly appreciated.

I am not much of an URP user, but I think that’s simply what URP does - single pass rendering approach, with obvious and documented limitations like this.
Switch to built-in, hdrp, or, you know, modify the URP.
