FortiADC 5.0.0 DH parameters change

Hello,

is there any way to change the DH (Diffie-Hellman) parameters somwhere for 5.0.0 version of FortiADC?

The FortiWeb has this feature in the CLI:

config system global

set dh-params 2048

end

The ADC is now using the 1024 DH bits. Why it is not 2048 at least?
