+      Program fuse data using a structured buffer in memory starting at 'addr'.
+      This operation directly affects the fusebox and is irreversible.

+      The structure of the buffer should contain all necessary details for
+      programming fuses, such as the values to be written to the fuse, optional
+      metadata for validation or programming constraints and any configuration

 Configuration:
