Yes this possible to do by code

In you main activity add the following code

BluetoothReceiver myreceiver = new BluetoothReceiver();
var intentfilterparingrequest = new IntentFilter(BluetoothDevice.ActionPairingRequest);
RegisterReceiver(myreceiver, intentfilterparingrequest);

In your broadcast receiver write following code, if not create a new broadcast receiver

public class BluetoothReceiver : BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {
        string BLE_PIN = "0000";
        var action = intent.Action;
        switch (action)
        {
            case BluetoothDevice.ActionPairingRequest:
                BluetoothDevice bluetoothDevice = 
              (BluetoothDevice)intent.GetParcelableExtra(BluetoothDevice.ExtraDevice);
                bluetoothDevice.SetPin(Encoding.ASCII.GetBytes(BLE_PIN));
                bluetoothDevice.CreateBond();
                break;
        }
    } 
}
