As per R&D:
With the current design, there is no other way to achieve what you are asking, other than unchecking and revoking the "Settings" functions access for the group. Unchecking this option would make the below menu options to disappear from the left-hand menu.
If your users do not use the above first 3 options you can proceed with the solution already provided otherwise this needs to be taken up as an enhancement .
