Well, I thought there is a bit to be configured... I guess, the easiest way is to enable RDP protections. However, I found that this can be done by modifying the firmware on the microcontroller.
Please take a look at this package that may help you

I checked that but If I want to make any changes in JTAG functionality. If I want to make lock and unlock Jtag cryptographically then would board allow me to do that ? like we can make changes in Cerberus tool for other board in order to achieve that. Is there anything like that on STM board ?Can you please guide me to that ?
