STM32G0B0 datasheet DS13565 Rev 3 in Chapter 3.6 Boot modes tells:
"• USB on pins PA11/PA12 (except for STM32G0B0KE)"
This reads like DFU system bootloader is not available. However AN2606 Rev 64 has no restrictions for DFU bootloader on STM32G0B0.
Is the datasheet wrong or at least missleading or does AN2606 miss a clause for STM32G0B0?

If you have parts you can presumably determine the size of the System ROM/FLASH, and the content.
I'd probably look at the Vector Table, and those associated with USB usage.

At end of pin table see in ds :
So STM32G0B0 has USB boot, but not in 32pin STM32G0B0K .
