Point-fixes are available for some versions, as explained directly below. Further down is a registry key to do this from version 7.5 SP1 onwards.

As many have shown interest in removing this button from the Portal, this release is provided.
To apply the Point-fix follow below steps:
NOTE: This fix has not undergone full QA testing, and thus is provided "As is".
A new point fix for 7.1 SP2 MP1 has been created and attached to this article.
Symantec Development is working to develop a permanent fix in the next major release.
A similar functionality to disable the "Request Unlisted Software" button from the Software Portal is available starting from 7.5 SP1 release. Several Registry keys have been added to hide / unhide the button.
From 7.5 SP1 onwards it is possible to disable the button "Request Unlisted Software" by adding the ‘DisableUnlisted’ String value with a value data '1' on the SMP server.
To restore simply remove the whole registry value added.
NOTE: For ITMS 8.1 the same registry key mentioned above works without the need for a special pointfix. The "Request Unlisted Software" button becomes greyed out.
Symantec Engineering is tentatively working on UI changes to move this option into the UI in a future version.
