@Alberto: Thanks a lot for your help! There is no such setting in the
BIOS of the Thinkpad X1 Extreme. I can either select discrete only or
hybrid cards. I was finally able to get prime-select to switch to intel
but the rate remains at like 20W which is essentially the same as using
the nvidia card. I am also not able to connect to an external screen via
the on-board HDMI port which is another issue I never had to deal with
in a Thinkpad (usb-c to HDMI adapter does not work as well).
