Previous to Moto z2 it worked with trusted voice , face etc but Moto z2 seemed to be more restrictive. Yet iPhone x let's you use a trusted face on lock screen with same lock screen policy , it seems to be part cell phone vendor part Google policyThat's a Google Security policy. Nothing you can do about it, except post on the Google Support site and see what Google engineers have to say.
Can you use Smart Lock options with your employer's Group Policy? On Body Detection, Trusted Place, Trusted Voice, Trusted Device? That's how Google allows us to use Hands Free commands and Voice Actions with an active lock screen. I use a lock screen and Trusted Device and that unlocks my phone automatically. I use Trusted Voice and Trusted Place on my wife's phone and that unlocks her phone when using Voice Commands.
