You can by just updating the whole array :

yourArray.removeAt(0); //yourArray is the array in the firestore before changing anything
doc("docId").update("Array" : yourArray);

To remove an array inside Firebase Firestore. Try the following function:

docRef.update({
   array: FieldValue.arrayRemove(''); // Here add your Element ID which you want to remove it.
});

Notice : This method only works with simple array like ["test","test"] not array with objects.
