Freesync with Nvidia

I recently had an idea while playing the latest WoW expansion. In the game and in a few others these days is the ability to select the rendering GPU. I currently have a GTX 1080 Ti and a Freesync monitor. So I added an AMD GPU I had on hand and connected my Freesync monitor to it. In this case it's a Radeon Pro WX 4100.
With the game displaying and rendering through the AMD GPU Freesync worked as expected. When switching to rendering with the Nvidia GPU Freesync continued to work flawlessly as verified in the monitor OSD while the game was undoubtedly rendered by the 1080 Ti.
This leaves an interesting option to use Freesync through an old AMD GPU. I'm sure there is a somewhat significant performance drop from copying the display to the other GPU but the benefits of Freesync may offset that.
My next thought was to try the the GPU selector that Microsoft added in 1803 but I can't convince it that either gpu is a Power Saving option. https://imgur.com/CHwG29f
I remember efforts in the past to get an egpu to display on an internal Laptop screen but from what I can find there's no great solution to do this in all applications.

I also edited my MG279 to 56-144hz range. Still works great.
