STM32N657X0 NUCLEO — SAU Configuration issue(TrustZone + RIF configuration issue)

Hello ST Community,

I am working on the NUCLEO-N657X0-Q board with a TrustZone project configured in STM32CubeMX with three contexts: FSBL, AppSecure (AppS), and AppNonSecure (AppNS). The FSBL is working correctly and jumping to AppS successfully.

I was having an issue with the SAU Configuration. As per the wiki article, "How to start with RIF on STM32N6 MCUs"  https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_RIF_on_STM32N6_MCUs
I configured the SAU region. 
I configured the FLEXRAM, AXISRAM1 and AXISRAM 2 in STM32Cube IDE. But it stays disabled when I tried to generate code. My partition_stm32n657xx.h file looks like :

How to resolve this issue?
