Programming esp32 without ESP-IDF and build automation tools

[glebonelone]

How i can program esp32 without ESP-IDF and build automation tools ? (using only esp32 toolchain , esptool.py and command line (and something else)) Is it even possible? If it is possible, how can i do this ?

You can. If you run 'idf.py build' on your project, the last line spits out the esptool.py command line you can use to flash the program. Copy-paste the binaries mentioned there to the computer you want to program the modules on, install esptool.py there and use the command line to flash it. I think for Windows we also have a GUI-based flashing tool somewhere you can use.
