I also have multiple leds that require external PSU, so I will have a power supply providing power to all the circuit and to the ESP32-S2 aswell (5V...

Thanks for the answer. So SPIs SPI2-3 aren't managed internally as one but instead and I need to setup two SPI: SPI2 or HSPI and SPI3 or VSPI for a total of two SPI x 3 lines (MOSI, MISO, SCK) = 6 lines, and then attatch 6 CS to SP2 and 3 CS to SP3, is that right?
