I would really like to disable the “Backup your recovery code” notification. I use a hardware wallet, so I definitely won’t back it up via Metamask.
The fact that I can’t dismiss it hinders the usability of the extension too.
Welcome to the MetaMask Community @lordvader!! 
Your MetaMask wallet also has a seed phrase associated with it. You will want to make sure that you securely save and store this seed phrase as well. The only way to remove the prompt is to actually view and verify that you have securely saved and stored your seed phrase.
Remember: NEVER give your seed phrase to anyone for any reason. We, MetaMask Support, will never ask for it.
