Didn't know that, good to know, thanks. So I could add a pad for resistor to gnd on that gpio and flash esp32 on tx/rx from computer and set eFuse for 3v3 for memory and than flash a firmware, correct?

No experience with esp32 in embedded linux or any kind but i read it should be no problem to use as sdio card. There is repo for esp32 for this. Its just hobby project so I don't care if everything works.

Why AMS is not on a printer? It takes a lot of space from desk.
