How to remove audio track from B-roll video permanently (not just unlink/delete)

Hello everyone, I came to ask for your help once again.

I have a request to send my short video project to a business partner of ours, this is the first time I was asked to do that, and there are things I was not thinking about when we recorded the clips that now seem to be a problem.

Normally when recording there is a lot of talking in the background of B-roll clips that we use for the video (videographer talking with the talent / producer), and I would not want to "share" these talks with anyone editing the video after us.

Is there a way, to remove audio track completely from all those B-roll files in the assets pannel permanently (basically if I can mass-edit those RAW recorded b-roll files and detach and then remove audio from them, so the person editing the project after me has no access to the audio from the raw files), The audio from those files is not even used in the project at all, I only drag in the video portion of those files anyway when I edit.

If there is no such edit option, what would be the easiest way of achieving this? Editing each of the B-roll clips one by one by exporting video only portion of the file and re-linking the edited file to the original project?

Thanks in advance for anyone replying.
