Description

This article describes while setting up additional SSL/TLS load balancing options, such as SSL algorithm/mode/versions, there is no option to see the following:
 

# config firewall vip
# edit test
new entry 'test' added
(test) # set type server-load-balance
(test) # set server-type https
(test) # set ssl?
ssl-hpkp Enable/disable including HPKP header in response.
ssl-hsts Enable/disable including HSTS header in response.

Solution:

Ensure the firewall inspection mode is in Proxy mode.
 

# config system settings
#(settings) # set inspection-mode proxy
#(settings) # end

# config firewall vip
# edit test
(test) # set ssl?
