There are a couple of ways to control faxing on the acocunt.

At the phone numberlever - under Phone System > Phone Numbers - select the number in question and you can control what type it is:
 

As to the user, that’s the on the User Details:

You can also take out the faxing in the Roles, under Users.  I would copy a Role and then make the changes to the new Role for everything you want/don’t want the user to have.  Then a quick Template to assign to a group/subgroup - or just change the Role on the users Settings/Security tab.

Now if you are talking about controling it over the entire account - that would be a question for your account rep.

Hope that helps.

going to mention 2 other methods
1st method
More > Account Settings > General Settings > Fax Settings (pic bellow)

2nd method
reach out to support and ask them to remove the Fax Icon from the app - only RC can do this.

 

​@Criddell If either of these solutions helped you get your fax sorted, we would appreciate it if you marked them as “best answer” so other folks can find the topic.
