How to access Upper range OTPs STM32MP153A?

[DLiu.4]

I'm having trouble finding documentation on how to access the upper OTPs by the unsecure world. I see that I have to manage exceptions by using STM32CubeMX but its not very clear on how to manage the exceptions using STM32CubeMX.

Hi DLiu.4 (Community Member),

The unprotect OTP feature is not supported by CubeMX. Please refer to this page, you need to update the DT accordingly.
