As of my last knowledge update in January 2022, the term "meta account" wasn't specifically associated with any particular feature or setting on Facebook. However, if you mean removing a connected account, such as a linked Instagram account or other thirdparty apps, from your Facebook account, you can follow these general steps:

To Remove Connected Instagram Account:

1. *Open Facebook:*
Log in to your Facebook account.

2. *Go to Settings:*
Click on the arrow in the topright corner of Facebook and select "Settings & Privacy" "Settings."

3. *Click on Instagram:*
In the left column, click on "Instagram."

4. *Remove Account:*
Under the "Accounts used by other apps" section, you should see your connected Instagram account.
Click on "Remove Account" next to your Instagram account.

5. *Confirm:*
Confirm that you want to remove the connection.

To Remove Other Connected Apps:

1. *Go to Settings:*
Click on the arrow in the topright corner of Facebook and select "Settings & Privacy" "Settings."

2. *Click on Apps and Websites:*
In the left column, click on "Apps and Websites."

3. *Review Active Apps:*
You will see a list of apps and websites connected to your Facebook account.
To remove an app, click on the app name, and then click on "Remove App."

4. *Confirm:*
Confirm that you want to remove the app.

Please note that the steps and options might evolve, and Facebook's interface could change over time. If you are referring to a different aspect of a "meta account" or if there have been updates since my last knowledge update, you may want to check Facebook's official help center or support pages for the most current information.
