How do you port openssl_ciphers=DEFAULT@SECLEVEL=0 to wpad-mbedtls?

Previously I was using wpad-openssl, with this line in my wpa_supplicant.conf, openssl_ciphers=DEFAULT@SECLEVEL=0 Now I want to move to mbedtls, how do I port that line? Without it I'm getting MTLS: invalid tls_disable_tlsv* params; ignoring 10g-2: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 13 (TLS) selected MTLS: mbedtls_ssl_handshake: SSL - A fatal alert message was received from our peer (-0x7780)
