Unable to remove leftover file after software deletion

Hello,

Hope someone can help.

I recently uninstalled Bitdefender from my MacBook Pro 16" M1 Max for various reasons. After a successful process and manually cleaning up numerous leftover files in the Library and hidden Library, I have one file that states I do not have permission to delete. It is a 32mb file in Library>Systemextensions>com.bitdefender.vpn.neprovider.systemextension

I have tried changing permissions in this file without success.

Is it possible to delete this file in some process unknown to me?

Thanks
