S32K3 Cyclic Wakeup and Secure Boot

[Verifono]

My requirement is to monitor a sensor while keeping average current consumption < 150 uA. The uC  shortly powers up the sensor every second and reads the sensor's binary value on a digital input. This can be solved with a cyclic wakeup from Standby mode.
My current understanding is that a normal boot sequence is performed on standby exit, which includes secure boot. The measurement could be finished in microseconds, but secure boot extends the Run mode to many millisecods so that the average current is too high.
- Secure Boot is not necessary after Standby. Can it be bypassed?
- Is there a way to switch-off the cores and peripherals without boot sequence after wakeup?
- Any other solution?

This is exactly the hint that I was looking for. Thank you very much!

Secure boot is being skipped after fast standby exit as you can see in the following diagram:

Normal standby exits goes over secure boot sequence. If it is not the key point of your question, please clarify.
