I have been following this guide to attempt to calibrate each sensor but for some reason, it doesn't work on my nano 33 IoT. It does work on my regular Arduino that has EEPROM. The IoT has no EPROM but it does have flash memory so shouldn't that work the same.

This looks like the error you should expect to see when using an nRF52 board with SPI flash.
It's OK to see Failed to read file / No calibration loaded/found (we haven't made one yet!)

Can you paste in the full output from your console?

nano33 iot does not have external flash on it - and its untested, so you will not be able to autocalibrate/store the data.
