Same issue for me. Power consumption ~10W higher than normal on intel mode since some update around that happened around this past month. Previously had to use the command echo 'auto' > '/sys/bus/pci/devices/0000:01:00.0/power/control' (from powertop's tunables) to shut down the dGPU but otherwise worked fine.
Ubuntu 18.04.3, sddm
Legion Y530, Nvidia GTX 1050M
Tested on kernel 5.3 and nvidia 430.50 and on a fresh installation with default kernel and nvidia drivers
