F5 APM integration with Google (Cloud) MDM (Chrome OS)

Hi,

We have deployed a large fleet of Chrome OS and I would like to enhance the security to only authorize VPN connectivity from genuine Enterprise enrolled Chrome OS devices. In other words, I am looking for a solution for APM to query via API the Google Cloud MDM and check if the device is enrolled with us.

I found articles for AirWatch, MaaS360 (who uses that??), and Intune but none on Google MDM although F5 claims it is working closely with Goggle for API level access.

Anyone can help? Thanks in advance
