@MikeMcQ & @rg305 I come back to tell that I have identified the problem (I think)
Into the main config files I called the optional conf.d/files.conf at the begining. But, as mentioned here https://httpd.apache.org/docs/2.4/sections.html the order of parsing instructions, directives, etc..., indeed files included is important.
So I had rewritten totally the http.conf file and now everything works. Or almost I just have an error
TLSv1.3 (IN), TLS alert, unknown (628):
- OpenSSL SSL_read: error:1409445C:SSL routines:ssl3_read_bytes:tlsv13 alert certificate required, errno 0
- Closing connection 0
curl: (56) OpenSSL SSL_read: error:1409445C:SSL routines:ssl3_read_bytes:tlsv13 alert certificate required, errno 0
But at least with curl I see the port 443 opened and handshakes works :

It should not be a big issue now. I'll find it
