Because to be RFID (13.56MHz) reader you need to have specific HW stages to drive the field, detect something present in it etc. (in ISO14443 language simply implement PCD role to detect and talk with PICC). This seems never been in nRF52 scope so there is no way around it, this HW won't read other PICCs (= tags as you call it).
