Need steps to configure DBFW with F5 Load Blancer

Here is a Situation :

I have configured Audit vault in High Availability setup and we have 2 Firewall servers which are stand alone .

The Clients requirement is to use the F5 load balancer to route traffic between the 2 firewall systems .

question 1 : Can this be done?

question 2: if yes, where and how can the BIG IP be configured to load Balance the traffic to the Firewall itself ( Not talking about configuring Big Ip host in the AV)

Secondly:-

Client wishes to register the same host in the 2 AVDF  systems ( primary and DR ) can this be done.

I understand that a different agent home can created and agent can be installed on the DB for another system .But will it have any effect on the system and Auditing . Any help will be greatly appreciated .
