What are some examples of not configuring outbound rules in AWS network ACLs?

Because the network ACL configuration in AWS is stateless, I think you need to configure inbound and outbound rules respectively, but could you tell me an example of a pattern that only sets inbound rules?

For example, I understand that SSH, HTTP, and so on need to get a reply from the client side, so I need to allow both inbound and outbound.

Do you mean that there is an example where the client just sends it and doesn't check the results?
