Let me re-use a description which I wrote for another customers in the past. See please below. Just always use the latest firmware and latest documentation. The versions mentioned in the text are not up to date.
And regarding secure debug - this is supported only via JTAG/SWD, not via UDS.
Regards,
Lukas

Installation:
First, we provide application note which explains how to install the firmware. Go to:
And select Documentation -> Secure Files. Here search for document “HSE FW install for S32K3xx”.
It’s also described in HSE-B Firmware Reference Manual rev. 2.2 which can be found in Secure Files section too. See chapter “3 HSE Firmware Installation”.
Then we provide this set of examples:
https://www.nxp.com/webapp/Download?colCode=S32K3_HSE_DemoExamples
After installation, you can find these two examples:
c:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Device_Configuration\S32K344_HSE_FW_INSTALL\
c:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Device_Configuration\S32K344_HSE_FW_UPDATE\
The INSTALL example shows how to install the firmware via IVT.
The HSE firmware can be downloaded from S32K3 Standard Software -> HSE Firmware:
https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-STDSW-D
Examples:
HSE DEMOAPP:
Can be downloaded from the same place as above:
It supports also S32K396.
There’s detailed description in the readme file, section “4. Setup”:
c:\NXP\HSE_DEMOAPP_S32K3XX_0_2_40_0\HSE_DEMOAPP_S32K3XX_0_2_40_0_ReadMe.pdf
It describes all the steps needed to make the demo work – including copying of HSE FW interface files etc.
Because the demo requires Lauterbach Trace32 debugger (it uses a custom menu in Trace32), the demo was ported to following set of examples which can be used with any debugger:
https://www.nxp.com/webapp/Download?colCode=S32K3_HSE_DemoExamples
HSE DemoExamples are written for S32K344, it must be ported to S32K396. The functionality is the same, it’s just necessary to create new project for S32K396, copy the source files etc.
RTD examples:
Autosar Crypto driver in RTD contains examples written directly for S32K396:
There are versions for EB Tresos Configurator or for S32 Design Studio IDE.
And there’s one example for MCAL crypto layer and one example for lower non-autosar Ip layer.
Secure boot
We provide Secure Boot application note including demo projects. It can be downloaded from:
https://www.nxp.com/products/S32K3
Application note can be found here:
Documentation -> Secure Files -> Secure Boot Application note v0.1.1.0 (AN744511)
Associated demo project can be downloaded here:
Design Resources -> Software -> Secure Files -> SecureBootAppNoteDemo (SW745310)
Next examples can be found in HSE DemoExamples already mentioned above:
https://www.nxp.com/webapp/Download?colCode=S32K3_HSE_DemoExamples
Documentation and trainings
HSE-B Firmware Reference Manual v2.3:
Can be downloaded from https://www.nxp.com/products/S32K3
Section Documentation -> Secure Files
This section also contains some HSE trainings.
HSE Service API Reference Manual:
Can be found on path like this after installation of HSE Firmware package:
c:\NXP\HSE_FW_S32K396_0_2_40_0\docs\S32K396_HSE_Service_API_Reference_Manual.pdf
Performance
See following sections in the datasheet:
