Can Digi MicroPython use SMBus interface?

I am trying to read an SMBus device with the Digi LTE cat 1 in micropython mode. I can read standard I2C sensors, but am having trouble understanding the requirements of SMBus and if they can be met using the digi library for I2C. Can the Digi MicroPython read SMBus in a native mode or will I need to write the interface from scratch? Thanks.
