Is anyone seeing random reboots of AVD VM's with no bugcheck events and no dump files?

We have 9 AVD pools in use with approximately 50 D16sv3 and D16dsv4 hosts and each week we may have 2 days where a host just reboots in the middle of the day and there are no bugcheck events or any helpful events logged and no dump file is produced.  When I check the azure activity log it shows a health event that a reboot was triggered from inside the virtual machine.  None of the users have the ability to reboot and there would be an event showing the reboot by a logged in user or remote user but there are none. Has anyone seen this?
