System76 nvidia optimus laptop not switching to nvidia consistently

Hello, I’ve purchased a system76 oryx pro which has an integrated gpu and a discrete gpu and am having issues to get the nvidia card to switch consistently when I reboot my machine. I know that this is a nvidia optimus situation and I’ve installed the nvidia drivers from negativo which is supposed to switch to the nvidia gpu automatically based on the software. I have to reboot it about 5-15 times for the nvidia card to finally be switched. Not sure what is causing this. It is working without issues on their own popOS! though.
Someone any ideas?

Much appreciated.
Thanks
