STM324x9I-EVAL SPI port available?

When running STM32CubeMX and selecting this board it shows all SPI ports as unavailable (red X) except for SPI4 which has very limited functionality.

Am I interpreting this correctly? There is no way I can use any of the other SPI ports? (Even when not using some of the other peripherals?)Thanks!

I'd trust Cube (or MicroXplorer) to figure the pin conflicts more efficiently than I can do it with a pen and paper. You'd have to figure out where the conflicts are arising, and back out those associations.

Full featured boards like the STM324x9I-EVAL are there to demonstrate the function of already attached peripherals/hardware. Pins are already over subscribed to the point it has an I2C base IO Expander for some of the lower bandwidth IO/IRQ functions. Perhaps you need to have a more break-out level board, the STM32F429I-DISCO is not a good one, but seem to think WaveShare had a more open/plug-n-play type approach.
