Updating drivers on a GTX1650 + 1070 machine

I am going to restart my pc because I have a problem videos are not loading on a machine with 2 Gpus.

Now the problem is how do I update the drivers? For which one should I optimise?

I am running Xsplit currently and that works fine Blender worked before aswell but blender doesn’t open atm and videos don’t open/load in any sort of app figured it to be a driver issue which is why I now would need to know which driver to install on this setup.
