MDuino 42+ Ethernet and SPI

I am new to MDuino products and am trying to use the Modbus TCP (ethernet) with SPI to communicate with slave device. from the Mduino 42+ manual 9.4. It say "As the Ethernet protocol uses the SPI to communicate with Arduino board, both behavior cannot happen at the same time as the Ethernet would not work" Is that mean that I can only use either Ethernet or SPI but not both at the same time? is there a way to configure or program the Arduino so I can use both? if yes, is there a example of guide on how to do it? Thanks!
