Stop Bitdefender adding the ExtensionSettings registry entry for Thunderbird

My Thunderbird installation is managed via policies.json file.

If bitdefender is installed, it forces the registry entry HKLM\SOFTWARE\Policies\Mozilla\Thunderbird\ExtensionSettings

This forced addin does NOT work, as already documented in other posts. Additionally it corrupts all my configuration on addins. I can delete this entry, but few minutes later it comes back.

Is it possible to stop bitdefender adding this registry entry?
