Hello Legolas,
You can achieve active/passive configuration by configuring the load
balancer to redirect all traffic to the active instances.
Doing so, the passive instances will stay in sync in terms of session
but will never receive a hit.
I am however intrigued why you would choose this architecture.

IMHO this is not possible. Maybe someone more authoritative could confirm.
