Is it possible to write to the SD card through the USB connection on SKR Pro 1.2?

When I was using an SKR 1.4, I had an SD card in the slot and a computer hooked up to the SKR 1.4 through the USB-B connection. I would use this workflow:

• Change code on computer hooked up to the SKR 1.4
• Hit the "PlatformIO: Upload" button in VSCode, which would compile the firmware and send it to the SD card in the SKR 1.4
• Restart the SKR 1.4, which would load the firmware.

The SD card in the SKR 1.4 would show up as an external drive to the computer's operating system.

I'm trying to replicate that flow with the SKR Pro 1.2, but when the SD card is in the board and I connect a computer to the USB-B connection, the computer doesn't detect the SD card as an external drive. I've confirmed that I can plug the SD card into my computer, compile the firmware, move it to the SD card, put the SD card into the SKR Pro 1.2, restart the SKR Pro 1.2, and the firmware is updated. However, that's a significantly less convenient workflow for iterating on the firmware.

Is there a way to have the SD card in the SKR Pro 1.2 and a computer hooked up to the board through USB-B and access the SD card from the computer, like was possible with the SKR 1.4?
