ESP32-S2 SPI pinout using IO MUX?

Hi, I want to use the SPI capabilities of an ESP32-S2 (with external flash and PSRAM) to connect an RFM95W LoRa module but It is not clear to me what GPIO I must use to get the best performance. I have seen in the datasheet that I could use whatever GPIO but if I use the SPI2 or SPI3 taking the IO M...
