You do not want to switch off tls_advertise_hosts.
Check, where the Debian config scheme allows you to set the path names
for the crt and the key file and put your self generated crt and key
there. Watch the permissions on the whole path, Exim reads these file as
the Exim runtime user, Debian-exim on your system.
