hostapd and internal RADIUS

[hostapd user]

Hello everyone.
Can you please tell me if it is possible to partially use the RADIUS 
server built into hostapd: for example, my case - I want hostapd to 
establish a TLS tunnel with the suplicant by itself when using EAP 
TTLS/MSCHAPv2, but send the phase2 request (MSCHAPv2) to the external 
RADIUS server and didn't use the internal user database for this?
Is this possible?
Thank you.
