Hello,
If you're looking for actual FMEDA/DFA/FTA templates or examples, these are typically provided:
- Under NDA (Non-Disclosure Agreement)
- Through NXP support or your local FAE (Field Application Engineer)
You can find all safety related documents on NXP web page for S32K3 under secure files:
https://www.nxp.com/products/S32K3?ticket=ST-2386-bOAWTUGgQ9aB9hAx3KqTeCycCAc-nxp#myDocument

Since you have direct NXP FAE I recommend to ask directly for examples.
Best regards,
Peter
