Poor battery life and high temperature on laptop with NVIDIA hybrid graphics

## Prerequisites
- [x] I have searched open and closed issues for duplicates.

## Describe the bug
I use an Alienware m15 laptop that has NVIDIA Optimus. It should, in theory, prefer the Intel GPU and only use the NVIDIA GPU sparingly (video games, etc..). However, elementaryOS prefers the NVIDIA GPU which results in the laptop running hot and the battery life being non-existent.

### To Reproduce
Steps to reproduce the behavior:
1. Install elementaryOS
2. Use laptop
3. Notice laptop is oven and doesn't work on battery

### Expected behavior

I expect the laptop to use the Intel graphics the vast majority of the time. I previously used Fedora on this laptop which did that and it worked beautifully, no overheating, battery life was many hours versus a few minutes. Some applications automatically opened on the NVIDIA card, others required selection in GNOME (GNOME 3.36 has new UI that is available that lets you run apps on NVIDIA card)

## Platform Information
- OS: elementary OS
- OS Version: Hera
- Hardware: Alienware m15 w/ Intel Core i7 9750H, NVIDIA Geforce RTX 2060, 32 GB RAM
