certificates wpa-supplicant access-point radius freeradius

                          When connecting to a WPA Enterprise access point, operating systems like iOS and macOS display the server certificate to the user if it has not been seen before. However, on Linux, using wpa_supplicant, this prompt does not appear. I have configured wpa_supplicant using a .conf file, but I do not get the server certificate. Is there any way to obtain the certificate when connecting to the AP on linux?

This is one of the configurations I have used:

    network={
        ssid="ssid"
        key_mgmt=WPA-EAP
        eap=PEAP
        identity="your.username@example.com"
        password="yourpassword"
        phase1="peapver=0"
        phase2="auth=MSCHAPV2"
        ca_cert="/etc/ssl/certs/your_CA_cert.pem"
       }

And the usage of wpa_supplicant:

    sudo wpa_supplicant -i wlan0 -c /etc/tmp/network.conf -D nl80211 -dd
