Prime select is not turning off the dgpu in Ubuntu 20.04

Laptop: MSI GE40
dGPU: GTX 760m
iGPU Intel HD4600

Driver: Nvidia 440 installed via "Additional Drivers" GUI from default 20.04 repos.

When using "prime-select intel" the iGPU is being used however the dGPU is still powered on resulting in considerably more power usage and heat generation.

Installing and loading the bbswitch module and running "echo "OFF">/proc/acpi/bbswitch" does successfully power down the dGPU drastically lower power usage.
