PKA option is greyed out even it is supported in STM32H533

Hi,

 

I am working on NUCLEO-H533RE board. I am checking all the configurations before start of my work. As attached below, The datasheets says that PKA is supported when i opened .ioc file, It is visible as greyout. I am not able to activate it. Even i configured the clock configurations for the board. I am not able to find documentation regarding H533RE. mostly it was written about H563 or H573 series. Could you please also help me out regarding the documents.

Hello,

According to the message from CubeMx, you need to activate the RNG. I'm not crypto/security expert but this is what CubeMx is showing:

Activating RNG makes PKA available:
