Stacking multiple shields on microcontroller


I am using two shields (LoRa and Ethernet) on my arduino UNO. Both shields works fine individually but together they dont work. After seeing schematics, came to know both shields communicate with Arduino UNO through SPI. They both use the SS or CS pin of arduino UNO. Its digital pin 10.

Guys tell me a very simple solution as i am new to microcontroller.

Thanks in advance :slight_smile:
