Procedural Foilage Spawner - "..meshes don't yet support ..lighting.." A solution, once and for all?

I got this warning when building lights:

“Instanced meshes don’t yet support unique static lighting for each LOD. Lighting on LOD 1+ may be incorrect unless lightmap UVs are the same for all LODs”

on my landscape. I tried googling and from what I understand:
(1) Although the warning is on my landscape, it is talking about the foilage I created
(2) In most places there isn’t any answer.
(3) In the few places there is, people are told to not use lighting with foilage or LODs (specifically for grass is all I could fine).

My problem is, I’m using it for trees. Specifically, I used procedural foilage spawner, in order to create a forest.
Now I’m not sure, but I think I should still use LODs since I’ll have many trees, and most won’t be visible / will be from afar.
Also, Since trees are kind of big and static, they should have shadows and hence lighting.

So what should be done?

p.s.
I followed the procedural foilage spawner tutorial on UE site. I even used their content (from the open world demo).
