Uninstall local interface only

Hi

I have used the following script: sudo bash /usr/local/share/adsbexchange/git/install-or-update-interface.sh
However, I already had tar1090 and readsb running to provide adsb data to feed.
Having the tar1090 map twice is thus unnecessary. How can I only remove the local interface?
This in order to remove the local-ip/adsbx 

Thanks!
