I've tried asking on the Hashicorp Packer forums with no luck, but thought I'd also ask here. I’m trying to provision a Proxmox template using the Proxmox ISO builder, but the OS that I’m trying to provision only works with UEFI. Is there a way to have Packer set the VM BIOS in Proxmox to OVMF/UEFI so the OS installer can boot?
