Can I use MCP23S17 to drive a 8-bit parallel 3.5in TFT Display?

Hi everyone,

I accidentally bought an 8-bit parallel bus LCD display, however, I have no idea how to set it up for the PocketBeagle. I have the Explore BeagleBone book and it’s suggested that an MCP23S17 can be used to drive an 8bit bus using SPI, however, I cannot find any further information on how to interface with it to drive the display and use the driver. Could someone help by either providing some additional reading I can read through, or provide some solutions (even directly driving the display from the GPIO without the MCP23S17 chip). The driver which is being used by the display is the ILI9486.

The display: https://www.amazon.co.uk/gp/product/B07N4J85D6/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Thanks for the help!
