How can I remove the closes from the changelog message?

I am using a custom issueUrl for changelog generation, and I would like to know if there is way to remove the "closes issueNr" at the end.

When using this custom issueUrl, all commit messages are transformed to:
 - whole commit message, closes issueNr.
 
I don't want that. I just want to have a reference from the issueNr, and not the "closes" message, which is not always true.
