Depending on how the app was packaged this may\may not work.
On the Operations tab go to Software Management\Software Library. Select the service in question and on the Software Properties page check the value in the "Install Command Line:" If the value is RadiaMSI /i then you can add the MSI switch that calls a silent install - typically /qn. This switch needs to be in quotes so the complete install cmd would be RadiaMSI /i "/qn"
If your install cmd line is simply calling a batch file then the above won't apply.
