Have a look at Change VM Boot Order via PowerShell, that is the method to change the bootorder.

But it doesn't look as if EFI is an option you can select.

Even the 5.5 VirtualMachineBootOptionsBootableDevice object doesn't seem to have that option.

Update, I was too fast with my conclusion.

To change the firmware from BIOS to EFI you can do

$vm = Get-VM TestVM

$spec = New-Object VMware.Vim.VirtualMachineConfigSpec
$spec.Firmware = [VMware.Vim.GuestOsDescriptorFirmwareType]::efi
$vm.ExtensionData.ReconfigVM($spec)

How do you change the boot order with an UEFI machine?  I have the code for BIOS base VM, but I presume the syntax is different for UEFI VM
