UEFI Boot order options missing from Hyper-V host

i have 2 2012r2 hyper-v hosts. on 1 of hosts, have no options set uefi boot order, either on existing virtual machines, or on new ones. on other host, options available. have series of powershell commands run create gen 2 vm.  here output hyper-v host:

here's output bad host:

i unable add boot entries, or modify:

set-vmfirmware : operation not available.

so, wrong particular hyper-v host, don't know troubleshoot - ideas?

i removed hyper-v role completely, rebooted, re-added again , rebooted, , options there. wish didn't have that, fresh server build.
