help using ssPin

[EslamEldeknawy]

hello i'm using this library and already printed pcbs
i need to use pin D10 as input while the library uses it
but on pcb it's not connected to the shift register and the lcd working

I've found a solution for my issue
By editing Spi library and set ss,LOW
also from my code

Spi.begin(); digitalWrite (ss,LOW);
and i didn't set pin 10 as input but assigned a button to it and it worked :)
I don't know if this right or wrong
But my lcd doesn't use pin 10
