You can use the Installation Manager (SIO-GW IM) to extend an existing system by adding a new entry (line) into the installation CSV you used. Make sure the SDC PKG was uploaded to the IM and that there's connectivity between the IM and the SDC host you with to install and configure into your SIO system.

Another manual option is to manually install the SDC PKG and them to configure the driver using the drv_cfg file. you can read about it in the user/installation manuals
