Has anyone got a Linux distro running alongside ChromeOS on a Lenovo Flex 5?

After reading the positive reviews, I picked a 256 GB 5i model up on Amazon's excellent Black Friday deals.

If it's possible, I'd like to find a way to run a full Linux distro without losing ChromeOS. It's unclear to me if the existing methods like Crouton, Gallium, Breath have been shown to work with this device.

Has anyone here pulled it off? If so, how?
