Hide Attachments tab

Hello,

I want to restrict the ability to attach files to certain user groups, I have reduced maximum number of attachments to 1 (zero is not possible) and reduced the max file size to 0 Byte and deleted all the extensions:

With this configuration the user is still able to try to upload a file even if there's an error after that:

But I'd like to hide the Attachments tab to those users in that user group, how can I do it?

No, because I want to allow other user groups to upload attachments

Solved. It wasn't the Everyone group but another group where the user was a member.
