If you are referring to a domain that you have added to your Facebook account, it is possible to remove it if you are the admin or owner of the account. Here's how:
- Log in to your Facebook account and go to the "Settings" menu.
- Click on the "Business Integrations" option and then find the domain you want to remove.
- Click on the "Remove" button next to the domain name.
- Confirm that you want to remove the domain by clicking "Remove" again.
Please note that if the domain is associated with a Facebook pixel, this will also be removed when you remove the domain. If you have any active ads that are using the pixel, they may stop tracking conversions once the domain is removed.
If you are not the admin or owner of the Facebook account, you may need to contact the account owner or admin to request that the domain be removed.
