Progressive Gpu Baking

When i use this feature it uses my intel uhd graphics while I already have RTX 2070 on my laptop ,is there a way to manually change it?

Okay so the actual problem is when I use Progressive gpu lightmapper it switches ot progressive Cpu on it's own , can anyone tell me what's causing this?

If the scene data is too big to calculate on GPU, it automatically changed to CPU mode.

If you want to manually select what GPU is used for lightmapping, use commandline parameters:
