I only have a breakout board with BNO055.
I try to connect to Development Desktop with usb uart dongle but it don't work.
Isn't that possible or did I somthing wrong?

There were more HW boards, could you describe more infromation which HW boards you used? How did you use them? What was the problem?

The BNO0 55 has an UART Interface, why it isn't possible to use it with Your Software? The sense is costumers has to buy expensive Hardware?

You can't directly use USB serial to BNO055 because BNO055 is 3.3V, so you need level shifter.
We already open our shuttle board schematic, UART interface and Driver as below.
If you can design hardware properly, technically you can design your own hardware with BNO055 and test it.
However, there is always some possibility to have hardware issue.
Why not only bosch, but all chip vendors have their own development kit is for customer to verify their software first, then test with their own hardware.
