S32K388 GPIOs safety mechanisms implication Apart from redundancy SM4.REDUNDANT_IO

Hello Team 

We are planning to use S32K388 in highest ASIL rated project 

I am using my GPIOs to enable power supply's and some safety critical circuits,

I understood the suggested safety mechanism in safety manual of S32K (SM4.REDUNDANT_IO ) 

But unfortunately i can not use redundant pins due to GPIO pin usage limitation 

in this regards, is there any other safety mechanism that you can suggested or is it capable/support for GPIO self test during every wakeup and Turn_ON of the ECU

S32K3 FUNCTIONAL-SAFETY-SYSTEM-BASIS
