Data on Serial2, even though not initialized #1550
Description
Hardware:

Flash Frequency: 80Mhz
Upload Speed: 115200
Description:
For our application, we have used RX2 and TX2 on the DoIT ESP32 board (GPIO 16&17) for other purposes. This worked until recently, but not it seems, there is serial data being sent on those pins, even though I haven't initialized anything (i.e. I use an empty sketch).
I understand that there is the boot information on the first serial port, with which I am fine. But is there any way to prevent action on the other serial ports?
Sketch:
void setup() {
}
void loop() {
}
