The Flash of STM32WB55CGU6 Chip Can't Read and Write Normally，A sector is protected by CPU2. CPU1 can not access this area normally. How to switch to CPU2 to read and write this area through DWG or other methods?

FLASH address: 0x0800 0000~0x080F 5FFF, CPU1 (cortex-M4) can read and write to its normal access, address 0x080F 6000~0x080F FFFF is protected by CPU2 （cortex-M0）and read and write.

Any sector protected/secure for the CPU2 usage is not accessible by any other way, neither in read nor in write mode. and so no debugger access is allowed. ​CPU2 is only executing ST protected code. As a user cannot access this code to modify it, it is not possible to change this situation.
