I am adding a new answer with some alternative information - this might be useful if the scope of the modifications you need are larger than just a feature. See the end of the answer for a description of "transforms".
First, here are some screen shots so it is clear how to get the feature names. Here is a screen shot showing how you can find the feature names using Orca:
Here is a couple of screen shots combined to show you how to see the features by running the MSI file itself. Dialogs and dialog sequencing can be changed for each MSI, but overall the concept is similar. Find the "Custom" dialog or just run the setup clicking "Next" until the feature list appears. Some setups have no feature list at all in the GUI, and then you need Orca or you can read the log file which you did.
Other, commercial installation tools or a trial installation of these (can be easier to install than the full SDK which is required to get Orca) can also be used to view the contents of an MSI file.
Finally: another way to modify what is installed by an MSI, as well as making other changes is to use a transform - a database modification snippet, or transaction that is applied to the original database to make changes for installation.
