Remove the default set of portlets in user dashboard

[sverbois]

In Plone 5. The user dashboard is initialized with two user portlets, a portlets.News and a portlets.Recent.
How to change this behavior ?

In my use case, I never use user portlet. The dashboard contains only group portlets.

Hope that helps.

list_dashboards = ('plone.dashboard1', 'plone.dashboard2','plone.dashboard3', 'plone.dashboard4')
group_id = group.id
user_id = member.id

for name in list_dashboards:

    column = getUtility(IPortletManager, name=name)
    
    if column is not None:
    
        # Begin Delete Group Portlets on the Dashboard
    
        category = column.get(GROUP_CATEGORY, None)
    
        if category is not None:
            
            manager = category.get(group_id, None)
