I have to disappoint you, you won't find MISO and CS pins in I2C device and display from pictures is IIC standard.

Also documented in the datasheet of the display driver that it is in fact a SPI port https://www.rhydolabz.com/documents/33/ST7789.pdf.

SDA is MOSI (see working initalization here: https://github.com/Bodmer/TFT_eSPI/blob/master/TFT_Drivers/ST7...

I have a bunch of ST7789 1" display modules, which I have been trying to make work with the lvgl_example. https://ipfs-pin.com/ipfs/QmUeNJbajSxzKYdAQaHbci33w2HjZWdREPbDb6vAVEPW21/IMG_20191021_092545.jpg https://ipfs-pin.com/ipfs/QmVfbDxbGZsNtSYAG9zpv66Ct1hVq3f6psB4QXc3eBRxqa/IMG_20191021_092556.jpg ...
