Hiding the 'Get Support' icon

Hi All,

I'm Ramli from NCSI Brunei and I'm quite new to SAP. I'm more on BASIS support . I need some Expert/Guru on how to hide the 'Get Support' Icon on the web portal. Our user are Mindef Brunei and they requested to have the 'Get Support' icon to be removed or hide it so that their user won't click on it. This is because their SAP system is not connected to the internet due to security issue. They are using SAP Enterprise Portal 6.0.

I really appreciated the feedback and resolution, thank you in advance to any comment or feedback.
