Today we tested it with an oscilloscope and the spikes from ESP32 are everywhere. Looks like DC-DC convertors are not right solution. Just between two grounds, each at other side of PCB, we measured around 10mV. That is not OK. The circuit must be redrawn - I will use LDO instead. ESP32 is very bad designed ... the worst chip I ever worked with, but I need WIFI and Bluetooth :(
