In ArcGIS Pro, the buttons in the Layers group on the Map tab are unable to be deleted when customizing the ribbon.

Additional Information

Workaround

Delete the Layers group and create a customized group by adding in the buttons from the Layers group which are still desired.

For example:

<updateModule refID="esri_mapping">

   <controls />

   <tabs>

    <updateTab refID="esri_mapping_homeTab">

     <insertGroup refID="newGrouprefID123" />

    </updateTab>

   </tabs>

   <groups>

   <insertGroup id="newGrouprefID123" caption="New Layers Group" keytip="Newly created group with the layers buttons that can be customized.">

    <button refID="esri_mapping_addDataButton"/>

    <button refID="esri_mapping_simpleLayerGallery"/>

    <button refID="esri_mapping_basemapGallery"/>

   </insertGroup>

   <deleteGroup refID="esri_mapping_mapGroup"/>

   </groups>

  </updateModule>
