How can outgoing PING be disabled in a Fortigate?

Hi everyone, 

I had tge disabled PING in all interfaces and also created a rule to disable PING and PING6 in firewall local-in-policy. Incoming ping requests from otger devices to the Fortigate are blocked but the Fortigqte is still able to ping to other devices both in the LAN and in broader internet network (e.g. 8.8.8.8). Is it possible to disable outgoing ping requests?
