If you are using an external RADIUS server (FreeRADIUS), none of the EAP
configuration like certificates are used within hostapd.conf, i.e., the
EAP part is completely transparent to the AP in this case.

That's the way RADIUS works.

Then you cannot use RADIUS and the design you have with an external
RADIUS server is not going to be feasible.
