Hello we've got got a bunch of VM's hosted on two server 2016 servers. All VM's are managed using Hyper-V. We've got a requirement to enable Secure boot on all connected devices including VM's, we've got a single VM which we've been able to enable secure boot on. I've followed the suggestions in the following article, the problem is not all VM's have the Firmware Section & Under Security No Secure Boot just "Encrypt State and virtual machine migration traffic" https://blogs.technet.microsoft.com/dubaisec/2016/03/29/secure-boot-on-virtual-machines/
