I have a LoRa module hooked up to an XIAO ESP32S3 Sense board, I have code that use the LoRa module for long range image transfers.
The SPI pins on the LoRa module are connected as per the XIAO ESP32S3 pinout and I initialise the SPI with;
SPI.begin();
Works for me, no need to define SPI pins or stuff like that.
