Hero?

Still working in my NL trasition, I find this spot difficult Hero have a lot equity and bloker but villain PB twice, So here we dont have FE. Normally in NL is a push/fold spot never can call-fold there... We face KK-TT value range and not sure his bluff range in this size (unknown player)... So how work the treshold in PLO? Hope to see more clear this spot. Thxs
