Bootloader over DFU expose duplicate internal Flash interface

Hi, 

Following the original discussion here, this topic is split into a separate issue to remain aligned with Community guidelines and better visibility.

DFU mode
 

This processor can program the Option Bytes over DFU

 

DFU Mode

This Processor is totally misdesigned

It exposes the Flash memory 3 times
For me this looks like a severe bug.
If you have a STM32G0B1 with read and write protection there is NO WAY over DFU get rid of these protections.
