Azure IoT Certd service always shows auto renewal certificate message even if we disable it.

If I am not using the auto-renewal feature for the identity certificate, the system still shows a message in the logs(As shown in the code snippet below). In my opinion, if we don’t specify a setting, it defaults to 80%. Does anyone know if this is accurate? Additionally, how can I completely disable this feature?

`[cert_issuance.est.identity_auto_renew]
rotate_key = false
threshold = "80%"
retry = "4%"`


Additionally, I also found one similar bug, but it's closed.
