Need help hiding all drive except mapped drives

Question

hello experts,
I am trying to hide and prevent access to all local drives of an RDS server but still allow users to see mapped network drives and be able to access them like norma. I found the 2 policies that hide and prevent access to all drives, but that also applied
to mapped network drives.
is there any way to exclude the mapped network drives from this?
Thanks

I am not sure, but it looks that's what I need to change in the admx:
    <policy name="NoViewOnDrive" class="User" displayName="$(string.NoViewOnDrive)" explainText="$(string.NoViewOnDrive_Help)" presentation="$(presentation.NoViewOnDrive)" key="Software\Microsoft\Windows\CurrentVersion\Policies\Explorer">
      <parentCategory ref="windows:WindowsExplorer" />
      <supportedOn ref="windows:SUPPORTED_Win2k" />
      <elements>
        <enum id="NoDrivesDropdown" valueName="NoViewOnDrive" required="true">
          <item displayName="$(string.ABOnly)">
            <value>
              <decimal value="3" />
            </value>
          </item>
          <item displayName="$(string.COnly)">
            <value>
              <decimal value="4" />
            </value>
          </item>
          <item displayName="$(string.DOnly)">
            <value>
              <decimal value="8" />
            </value>
          </item>
          <item displayName="$(string.ABConly)">
            <value>
              <decimal value="7" />
            </value>
          </item>
          <item displayName="$(string.ABCDOnly)">
            <value>
              <decimal value="15" />
            </value>
          </item>
                    </item>
          <item displayName="$(string.ABCDQOnly)">
            <value>
              <decimal value="65551" />
            </value>
          </item>
          <item displayName="$(string.ALLDrives)">
            <value>
              <decimal value="67108863" />
            </value>
          </item>
          <item displayName="$(string.RestNoDrives)">
            <value>
              <decimal value="0" />
            </value>
          </item>
        </enum>
      </elements>
    </policy>
as far as the adml, I think I know what section I'll need to change, but I am not sure what to change there:
      <presentation id="NoDrives">
        <dropdownList refId="NoDrivesDropdown" noSort="true" defaultItem="5">Pick one of the following combinations</dropdownList>
      </presentation>
      <presentation id="NoViewOnDrive">
        <dropdownList refId="NoDrivesDropdown" noSort="true" defaultItem="5">Pick one of the following combinations</dropdownList>
      </presentation>
      <presentation id="PlacesBar">
        <text>Places to display:</text>
        <textBox refId="Places0">
          <label>Item 1</label>
        </textBox>
        <textBox refId="Places1">
          <label>Item 2</label>
        </textBox>
        <textBox refId="Places2">
          <label>Item 3</label>
        </textBox>
        <textBox refId="Places3">
          <label>Item 4</label>
        </textBox>
        <textBox refId="Places4">
          <label>Item 5</label>
        </textBox>
      </presentation>
any help :)
