Setting Option Bytes in Firmware with Secure Manager

Hello,

I am implementing Secure Manager V1.2.0 from X-CUBE-SEC-M-H5 in my firmware. I am following the instructions provided in the "How to start with Secure Manager (customized configuration) on STM32H5" page.

Is it possible to configure Option Bytes outside of the specific registers described on that page?

To clarify, I am developing firmware for the STM32H573VI and plan to incorporate Secure Manager V1.2.0. My non-secure application requires High-Cycle Data, which can be set through the EDATA1R_PRG register.
