After ArduinoIoTCloud 2.0.0 this library is used only for Arduino UNO R4.

Root CA for OTA legacy can be configured from the firmware using the included certificate bundle https://github.com/arduino/uno-r4-wifi-usb-bridge/blob/main/certificates/cacrt_all.pem

To use the new OTA storage service we need to use device certificate stored in nsv using https://github.com/arduino/uno-r4-wifi-usb-bridge/blob/aef6457c0f324686177a45792d62aa7ba27df8ce/UNOR4USBBridge/cmds_ota.h#L12
