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.

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