Have you tried adding this as a user-defined exception on your SEP client as a workaround? This is accessible from the SEP Client Console, under "Change Settings -> Exceptions -> Change Settings" and will exist on your machine only. Alternatively, you might try right-clicking on the SEP systray icon and clicking "Disable SEP".
These options are provided under the assumption that the administrator has not already locked these settings down. If these settings have been locked down (and are therefore not available) you're gonna have to ask the admins for available options (as you're not allowed centralised exceptions).
