AM4378: Secure id and memory

Part Number: AM4378

Dear Team

One of my customer is going to work on AM4378 or S version. The application is AC charger and the board based on AM437x will be part of the payment system. They want to protect their secure id and keep in the secure memory location. They normally don't need secure boot but will need only keep their id secured in a secure memory location. Could you please let me know if they can implement this using non-secure  AM4378BZDND80 or  they have  to use  AM4378BZDND80S  secure MPU?

Many thanks for your support

Best Regards

Yunus
