DRM kernel driver 'nvidia-drm' in use. NVK requires nouveau

I have the same issue, tried to install obsidian but somehow fail when starting it, tried to launch it with the VK_DRIVER_FILES=/run/opengl-driver/share/vulkan/icd.d/nvidia_icd.x86_64.json variable environment but fail to start, I try adding :

hardware.nvidia.modesetting.enable = true;
boot.kernelParams = [ "nvidia-drm.fbdev=1" ];

but fails too, and what’s even weirder is that somehow obsidian rarely success to start, why? I don’t know I litterally changed nothing to my environment between the two start session, not even rebooting.

There’s some related issues(I think) I found :

I think the issue is only related to chrome based app
