Change Beneficiary Life Event to allow Bene changes, but not enrollment changes

I need to allow users to change their beneficiaries on say Basic Life Insurance but not be able to unenroll from the plan (it's required). So, there will be no electability. I found this CCC (https://community.oracle.com/customerconnect/discussion/879854/custom-add-change-beneficiary-life-event-allows-change-in-coverage-in-redwood-ui?utm_source=community-search&utm_medium=organic-search&utm_term=Change+Beneficiary+Life+Event+) and this seems very creative so I will likely try, but I was curious if there was another way to do this?

As a visual, I would like the Unenroll button to be grayed out, but still allow for the pencil to be visible so that EEs can change beneficiaries.
