I want to use ADS1292r ECG shield with Arduino Uno (Seeeduino V4.2) and store the data in an SD card through an Wifi shield. But ADS1292r shield uses Digital pin 4 for "RESET" purpose, while the same pin is the "SD card select" pin for the wifi shield. So if I stack all 3 of them, the SD card can't be initialized. Is there any way to solve this problem? TIA

cut (or bend) the pin(s) which cause the problem so they don't connect between the shields
then use a jumper wire to connect to a different pin
I used this technique when stacking a mega, a lora shield and an Canbus shield
