how to cancel trail of NetGear Armor by Bitdefender?

I just purchased a NetGear Orbi router.  The set up program encouraged me to add security.  I did not realize by clicking on this option, I would be starting a trial period for Bitdefender Armor on the NetGear router.  Emails I get encouraging me to use Armor point me to the Bitdefender support web page for any issues.  But Armor is not listed as a Bitdefender product there, so that doesn't work.

Does anyone know how to cancel my trail of Armor?  Thank you for your help with this.
