Does Suricata have traffic shaping?

I didn’t find the relevant configuration.

what’s mean? Synthesis of chunk transfers?

Control the speed of flow. Limit the flow and burst of a connection that flows out of a network, so that such messages can be sent out at a relatively uniform speed. Traffic shaping is usually completed by using buffers and token buckets. When the sending speed of messages is too fast, the buffered messages are first cached in the buffer and then sent evenly under the control of the token bucket.

No it doesn’t as far as I know.

This could be very hard to implement in IPS mode. One could try to use netfilter methods if you’re running nfqueue mode to take care of that before.

Well, thank you very much.
