Change HSE Lifecycle

Hi,

I'm developing software based on S32K3xx Demo app.

In order to Update Secure Life Cycle, ADKP need to be is programmed.

After ADKP is programmed, the secure debug feature is enabled.

I got 2 questions:

Does the secure debug feature always enabled when HSE Life cycle is OEM_PROD/IN_FIELD?
Can secure debug feature be disabled when HSE Life cycle is OEM_PROD/IN_FIELD? (No debug authorization script needed)

Thanks a lot.

Here are two screenshots from the manual:

So, it is mandatory to configure ADKP when advancing the life cycle and it's not possible to disable secure debug because it's programmed to OTP.

Regards,
