Try disenrolling the device from the mdm. That may remove the lock state.

No use in disenrolling the device from mdm. It is still stuck in the lock state.

Hey @Conner Shaw,  

The Lock Device action uses a 6-digit System Lock PIN to remotely lock a macOS device without a Silicon chip. The Mac will go into an indefinite lock if the wrong System Lock PIN is entered repeatedly. It is an anti-theft feature built by Apple to protect your data if the device is stolen. Given this case, Hexnode UEM cannot disable the indefinite lock state, and we cannot do anything about it.

You’ll need to take the device into the Genius Bar or an Apple Authorized Service Provider with Proof of Purchase to recover the Mac.

Hope that helps you.
Cheers!
