I'm almost sure that the physical data transfer in the USB cable doesn't depend on the baudrate setting. This setting is just a parameter that the USB device can use the way it wants.
In the case the device implements a physical UART, then the setting controls the UART baudrate. In other cases it can be used for smth else. For instance, the Raspberry pi Pico interprets a predefined baudrate value as a command to switch to bootloader. Btw: what is your actual Arduino board?
