The RP2350 datasheet seems to be quite clear concerning that point

TX
Serial data output. Connects to the SPI peripheral SSPTXD (data out) and nSSPOE (output enable) signals described in the following sections. This is always a data output, independent of the bus role. The SPI peripheral controls tristating depending on chip select status.
RX
Serial data input. Connects to the SPI peripheral SSPRXD data input described in the following sections. This is always
a data input, independent of the bus role.
