Can you remove certain Life Events from drop down list under "Add a Life Event"

Hello - when a benefit admin adds a "potential life event" under Benefit Enrollment, there are many options that we no longer use or never have used. Are we able to remove life events that are no longer in use ? I have highlighted a few examples in the screenshot below that we do not want appearing in drop down list.

We tried to end date them under Programs / Plans but this does not remove the life event from the list. I also searched Lookups but cannot find anything related to this list.

Thank you in advance
