          It looks to me as if an ESP-01S WLAN WiFi module is installed under the plastic cover (under the stickers) and as if it is the back of a 3D printer. Then you could remove it and the host device would no longer have WiFi. If the host at least does not check whether it is present etc. when booting/starting and otherwise refuses the service
