EAP-TLS Certificate renewal

Tue Mar 8 16:51:59 UTC 2022

Hello,
I've setup Freeradius EAP-TLS for Android device following this tutorial by Techtalk (https://techtalkblog.ch/ubuntu-18-04-freeradius-v3-wifi-authentication/).
The first certificate I've issued will expire next July: Is there a way to extend the life of this certificate?
What are the best practices to manage certificates under Freeradius environment?
Thanks!
