What options are available under Thunderbolt Boot Support? If you only see Enabled and Disabled, have you tried both settings?

On Asus X99 we should use Thunderbolt header (THB_C) and we should not connect the middle and top pins.
Do you have any other Thunderbolt devices with which to test hot plug?
I have tried both options but with no luck
