I don't know if it is more a limitation for support effort by Red Hat or at all, also because here you can find a note for Ubuntu where it states it does support that role on Samba4: https://www.tecmint.com/install-samba4-active-directory-ubuntu/ So if you are "forced" to use CentOS you can try to inter-mix the information provided by the two links and see if it works.
