Marking pool down if 2 of 3 nodes are down.

I don't think there is an easy way to disable the pool without using scripts. If your intention is to try to prevent traffic from being sent to the 3rd member if 2 are down, you can try and utilize priority group within the pool.

It's not easy to do this without an external script but using a script will utilize your device resources, especially on VE editions.

I have created this as a temporary solution for a customer, using an external script. after the script, I have observed a rapid increase in the memory usage and removed it.
