eap_peer_config::client_cert2 field

client_cert2 - File path to client certificate file This field is like client_cert, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication. Full path to the file should be used since working directory may change when wpa_supplicant is run in the background. Alternatively, a named configuration blob can be used by setting this to blob://blob_name.
