when you are using our CONTROLLINO library to access RTC and standard Ethernet library then the chipselect signals are handled automatically by the libraries. So you do not need to take care about them in your code.
Maybe we can go one step back – which SD card shield are you using, please? Which signals are connected to CONTROLLINO?
Could you provide us part of the code where you initialize and access the SD card?
