Boot and Nvidia install problems

Hello
I had solved this problem with enable dGPU unstead DYNAMIC.
But the laptop use too much energy when using only NVIDIA card.

I have read all the posts of this thread : https://forums.opensuse.org/t/dedicated-gpu-cant-be-used/183940

but can’t find the good solution to not break the installed Tumbleweed.

Today, i have nvidia driver G7 installed and works fine.
