I believe I misunderstood you. When you said “How can we completely remove/disable the 2FA feature so no extra column shows up in Users screen” I thought you meant the wp-admin/users.php page, not the user’s profile page. You’d only need to make the change I mentioned earlier once to remove the column from the list of users on the wp-admin/users.php page.
For the users page in general, login to your site as an admin and go to the Login Security page (look under Wordfence in the left side navigation). On the Settings tab where it says “Enable 2FA for these roles” you can turn off the ability to use 2FA for any role you choose except administrators. Then those roles you deselected will not see any option to add 2FA to their account. I might add that only the administrators role is selected by default. If other roles were added they would have had to be checked by a member of your team.
