docs: <p>
  [VPC only] Removes the specified egress rules from a security group for EC2-VPC. This action doesn't apply to
  security groups for use in EC2-Classic. To remove a rule, the values that you specify (for example, ports) must
  match the existing rule's values exactly.
  </p>
  <p>
  Each rule consists of the protocol and the IPv4 or IPv6 CIDR range or source security group. For the TCP and UDP
  protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also
  specify the ICMP type and code. If the security group rule has a description, you do not have to specify the
  description to revoke the rule.
  </p>
  <p>
  Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay
  might occur.
