IS there way to change lightning data asset on runtime?

Hello.
I’m using additive scenes that overlaps with Realtime Gi. The problem is that I cant bake it together cause objects in different scenes are overlaping, and I want to load it in different configuration, I have MAIN SCENE and additive change scene SCENE A, SCENE B, SCENE C that scenes are never loaded at the same time I load it in Pairs MAIN SCENE + SCENE A / MAIN SCENE + SCENE B / MAIN SCENE + SCENE C/ I try to bake realtime GI in pairs and it works well then but it is impossible cause during baking unity overide in lightning data scenes that there is always only 2 scenes. So I figure it out that i just can bake it in pairs and then change lightning data asset for main scene and it works, but the problem is that there is no API that I know to change lightnind data asset for scene in runtime? BTW: I tried also to bake every scene separate way, but it seems like there is some bug that I reported that If I separeate bake terrain and spearate rocks od different scenes and then load it additive way, then rocks are darker than terrain but should be. so that solution is not great also because then rocks dont affect terrain etc. So How to change lightnind data asset on runtime or make any similar way? cause it seems like there is no proper workflow with realtime Gi and additive scenes, where scenes are in the same position and have obbjects in simmilar or the same position overlaping.
