Only if you have the newer board, with STLink chip using STM32F103CBT6 instead of STM32F103C8T6 (which also displays a "disk drive" when connected to PC).

And even then, you'd need to put wires on it, very carefully, see UM1472 page 13.

Thank you @Community member​  . I have "STM32F407G-DISC1" Board.

Can you help me with more details on how to set it up?

Have to wire manually, review Schematic in User Manual.

You can pick which USART you want to use. USART1 PA9/PA10 is not available, USART6 PC6/PC7 is, as I recall.
