Seeed Studio XIAO ESP32C3 (seeed_xiao_esp32c3): enable touchpad

Hi,

I got quite limited electronics knowledge, so bear with me x)

I got this board: Getting Started with Seeed Studio XIAO ESP32C3 | Seeed Studio Wiki
The page more or less claims that there should be a ESP32 touchpad available (further down, code snippet).

Am I reading that wrong? Or is it possible to override the board variant without breaking anything to try it? Or some other workaround?

Anyhow: thanks for this wonderful project <3
