How to partial disabling 'Open to Explorer' Ribbon Action

Question

I'm disabling, for all user Rights, the 'Open with Explorer' button in the SPRibbon with the following code:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
       <CustomAction
         Id="RemoveRibbonButton"
         Location="CommandUI.Ribbon">
              <CommandUIExtension>
                     <CommandUIDefinitions>
                           <CommandUIDefinition
                             Location="Ribbon.Library.Actions.OpenWithExplorer" />
                     </CommandUIDefinitions>
              </CommandUIExtension>
       </CustomAction>
</Elements>

reference

I intend to display only for user with 'ManageWeb' Rights, however the Rights attribute works in the opposite way(Removes ribbon to every SPBasePermissions set). Any idea how to make this work?

update

I try to remove, with the above code, and add a new custom action of the same button with the intended Rights, but it display to all user Rights anyway:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <CustomAction Id="AddExplorerButton"
            Location="CommandUI.Ribbon"
            Rights="ManageWeb"
            xmlns="http://schemas.microsoft.com/sharepoint/">
        <CommandUIExtension xmlns="http://schemas.microsoft.com/sharepoint/">
            <CommandUIDefinitions>
                <CommandUIDefinition Location="Ribbon.Library.Actions.OpenWithExplorer">
                    <Button Id="AddOpenWithExplorer"
                            Sequence="50"
                            Command="OpenWithExplorer"
                            Image16by16="/_layouts/$Resources:core,Language;/images/formatmap16x16.png"
                            Image16by16Top="-112"
                            Image16by16Left="-176"
                            Image32by32="/_layouts/$Resources:core,Language;/images/formatmap32x32.png"
                            Image32by32Top="-64"
                            Image32by32Left="-352"
                            LabelText="$Resources:core,cui_ButOpenWithExplorer;"
                            ToolTipTitle="$Resources:core,cui_ButOpenWithExplorer;"
                            ToolTipDescription="$Resources:core,cui_STT_ButOpenWithExplorer;"
                            TemplateAlias="o2" />
                </CommandUIDefinition>
            </CommandUIDefinitions>
        </CommandUIExtension>
    </CustomAction>
</Elements>

update 2 - solution:

In a custom ControlTemplate called in the .master:

    SPWeb currentWeb = SPContext.Current.Web;
    SPRibbon spRibbon = SPRibbon.GetCurrent(Page);
    if (!currentWeb.DoesUserHavePermissions(SPBasePermissions.ManageWeb))
        spRibbon.TrimById("Ribbon.Library.Actions.OpenWithExplorer");
