X-CUBE-SBSFU: Can you update firmware using USART DFU?

Hammad

All the provided examples are using USART YMODEM to transfer data. I know, that it really doesn't matter what kind of protocol you use as long as image is placed in a correct place in the memory, but I wonder if I can use DFU feature to update firmware and still use SBSFU. Additionaly is there any reference or resource that supports we only have to upload .sfb file and we can't use .bin file? If we have to use .sfb file only then what is the correct method of downloading it because we can't download .sfb file through cli as it doesnot support .sfb extension and same I am not able to upload it through STM32 CUBE Programmer.
