Hello!

 Because I need the GPIO 4 for steering the roboter, I want to
disable the flash light by removing some parts or connections.
 I found a video, but I didn't understand the instructions:
(903) ESP32-CAM How to add a GPIO33 output and disable flash LED - YouTube

Thank You for advice

The easiest way to permanantly disable the flash LED is to remove transistor Q1 which sits right next to the flash LED. GPIO4 goes to the base of Q1. Use a 30 watt iron, heat up the connections, and slide Q1 off the board. I know this works because I've done it. I use an ESP32 Cam operated by remote control to take pictures of birds visiting my birdbath. No flash to scare the birds and less battery drainage. I have before and after photos of Q1 if anyone wants to see them.

@johnyork That is strange that the flash was working since the 'standard' camera software has no connection to it and the new V4 software has a software/UI control of the LED.

SO, my question is what software are you using?

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
Sure you can learn to be a programmer, it will take the same amount of time for me to learn to be a Doctor.

I am using a commonplace sketch to store photos on a microSDcard inserted in the socket on the ESP32 Cam.. The microSDcard shares HS2 Data1 with Q1 that activates the flash LED. Unless you remove Q1, every time you take a picture and save it to the microSDcard the LED will flash.

@johnyork Ok, I use the standard espressif camera software that has been re-worked into Ver 4. The LED has software control.
