Bug with GPU selectionned by Unreal Engine

Hello.
I’m currently on a laptop with windows 10 & an nvidia 1050.
My issue is when I try to play to a game which is running on Unreal Engine, the game will always use the Default Integrated Chipset instead of my 1050.
I’ve already tried to configure parameters on the Nvidia panel, but the issue still here.

Please help me!
Thanks
