Thanks for the tip. But I cannot use that as I'm using the Arduino IDE / core.

Both HSPI and VSPI pins pulled down when using single SPI bus. Remaining pins cannot be used as GPIOs.
When using the SPI bus, the library is somehow enabling HSPI and VSPI at the same time, thus pulling down pins for both SPI buses. Those pins cannot be pulled up (therefore taking 8 pins to work instead of 4). I need to use the remaining pins as GPIOs (in this case, as interrupts with pullup configu...
