it's fixed thanks a lot
some time ago I had this issue and we were in a run and I rebooted the server now I know that is not needed.
# esxcli network ip interface list
this command showed that vmk1 and vmk2 were used
and when running this command
# esxcli network ip interface add -i=vmk0 -p="Management Network" -M="MAC Address"
Error message
unable to add vmkernel interface error was a vmkernel nic for connection point already exists
so I removed vmk1 and vmk2
# esxcli network ip interface remove -i vmk1
# esxcli network ip interface remove -i vmk2
After that options in DCUI were enabled.
