Use an extra defaulted bool parameter:

// primary template handles false
template
class circular_buffer {
   unsigned char buffer[SIZE];
   unsigned int head; // index
   unsigned int tail; // index
};

// specialization for true
template
class circular_buffer {
   unsigned char buffer[SIZE];
   unsigned char head; // index
   unsigned char tail; // index
};
