SPI.h Not Found when the sensor I'm using doesn't even use SPI? Apple Silicon on PlatformIO 6.1.16/VSCode using adafruit/Adafruit BusIO@^1.14.1

[CodeBradley]

I'm using a FLIP C3 board, which does not have SPI pins (only I2C, UART, digital, analog). I've tried declaring an SPI pinout in the pins_arduino.h file just to see if it fixes the error, but that didn't work. Suggestions online say to include SPI.h in the beginning of my script, but the same error occurs. It also continues happening when setting it in lib_deps.

What's the official way of resolving this?

There's claims that the problem is caused by how PIO scans the code, but the workaround does not help if the board I'm using doesn't have SPI. https://community.platformio.org/t/adafruit-busio-adafruit-spidevice-h17-fatal-error-spi-h-no-such-file-or-directory/14864/10
