A hack would be to loop the CANCEL to Kamailio again and forward it then
stateless. When forwarding the CANCEL stateless, you can add headers.

I see, so there is no way to append a header to the
CANCEL created by Kamailio?
I tried the onsend_route and branch_route, but none of them worked.

Does append_hf not work for CANCEL requests?
Correct: CANCEL is a "hop-by-hop" request where the proxy is a distinct
hop, i.e. UAC sends a CANCEL to the proxy, and the proxy sends a separate CANCEL of its
own on the branch that it initiated. This is in contrast to something like a BYE, and
most requests, which are end-to-end request that the proxy simply relays upstream as
received.
