You can update via fastboot. If your device is not detected, try this:

- Check if the fastboot software is correctly installed in your PC https://xiaomifirmware.com/downloads/download-platform-tools-adb-fastboot-r-26-0-0/
- Try to change USB cable. Use the original one if possible
- Change USB port. Old versions of USB ports (2.x and 3.0) work better than USB 3.1 or 3.2
