@hellogoodbye I was able to set it up today. Actually, I didn't need any extra software to get it working. I'm only using Drive File Stream. It's awesome how it works. When you add files to the drive, it stores them temporarily on your local drive. Once it finishes uploading the files to the Gdrive, it deletes the temporary files. This way you don't have local copies on your system.
I can confirm that it is working with Plex.
I've uploaded 600GB so far today.
