Yes, but it has nothing to do with Blynk per se… Just Arduino code that works with Serial.print() and String()
It works just as well with Blynk.virtualWrite()

int temperature = bme.readTemperature();  // get raw temperature value (normally displayed to three decimal points)
Blynk.virtualWrite(V0, String(temperature, 1) + " C");  // Display with only one decimal point and add in the C
