We have discussed it among the team. The support team would prefer to have ICMP enabled on servers since it would be easier to ping a server to verify if a server is online.
Moreover, you can disable/enable ICMP via the sysctl.conf file.
# echo "net.ipv4.icmp_echo_ignore_all = 1" >> /etc/sysctl.conf
# sysctl -p
In consideration with the query made by the support team, we have decided to kindly decline this request.
