Hi Norin,
I'm sorry to say that there is no way to do a minimal install. However, you can do an unattended install where you can choose what options you want to be "Local", "Absent", or "NoChange". I'm not sure if this is exactly what you are looking for but in order to customize it you'll need to change the template_spec.txt file. Here is a
KnowledgeBase that talks about how to do an unattended install for NI-DAQ, however it should work the same way for NI-488.2. Please repost if you have further questions.
