So I made one change. In the end of setup I put WiFi.disconnect(); and in drawCurrentTime() class I make little update, in the beginning i connect to WiFi and in the end I disconnect from WiFi and it is work.

void drawCurrentTime() {
  
  WiFi.begin(ssid, password);
  Serial.print("Pripajam sa na WiFi...");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  struct tm timeinfo;
  if (!getLocalTime(&timeinfo)) {
    return;
  }
  
  char timeString[9];
  strftime(timeString, sizeof(timeString), "%H:%M:%S", &timeinfo);

  char dateString[11];
  strftime(dateString, sizeof(dateString), "%d.%m.%Y", &timeinfo);

  int textWidthTime = strlen(timeString) * 18;
  int textWidthDate = strlen(dateString) * 18;

  int xPosTime = (tft.width() - textWidthTime) / 2;
  int xPosDate = (tft.width() - textWidthDate) / 2;

  int yPosTime = 160;
  int yPosDate = 190;
  
  tft.fillRect(xPosTime, yPosTime, textWidthTime, 24, ILI9341_WHITE);
  tft.setCursor(xPosTime, yPosTime);
  tft.setTextColor(ILI9341_BLACK);
  tft.setTextSize(3);
  tft.print(timeString);
  Serial.println(timeString);

  tft.fillRect(xPosDate, yPosDate, textWidthDate, 24, ILI9341_WHITE);
  tft.setCursor(xPosDate, yPosDate);
  tft.setTextColor(ILI9341_BLACK);
  tft.setTextSize(3);
  tft.print(dateString);
  Serial.println(dateString);

  WiFi.disconnect();
}

Now I am able to sending data true ESPNOW and update Day and time from NTP server. I still need to make som updates because it is not smoot but it's work. Here is output from serial monitor:
