How I can renew the maintenance certificate automatically in SMP?

In R3 systems, the maintenance certificate is getting expire every three months. I want to install maintenance certificate automatically using solman.

In solman using this job REFRESH_ADMIN_DATA_FROM_SUPPORT, I can pull the license from SMP to solman.

After that scheduling the task GET LICENSE DATA in /nsdccn, it will pull license from solman to system and also will be installed.

Now my query is renew the maintenance certificate automatically in SMP whenever the certificate is getting expired.

Could you please help me here how I can renew the maintenance certificate automatically in SMP?
