Using additional peripherals with the Round Display?

I’m interested in using the Seeed Studio round display to make a smart watch. I noticed all of the pins from the chosen Xiao microcontroller will be plugged into the board. Given this, is it possible to use additional peripherals with this setup?

pretty much you have to use IIC to communicate… or the USB cord… or wireless… Bluetooth

i suppose it would be possable to make a sensor card the size of the sd card and use it to communicate on the spi bus
