Hi Nicolas,

You can do this via Examine and InternalIndex and loop through these unpublished nodes and remove via ContentService.

try use IExamineManager https://docs.umbraco.com/umbraco-cms/reference/searching/examine/examine-manager

Probably inject IExamineManager

private readonly IExamineManager _examineManager;

try to get index internal

if (!_examineManager.TryGetIndex(UmbracoIndexes.InternalIndexName, out IIndex index))

And create search query

 var searcher = index.Searcher;
                    var criteria = searcher.CreateQuery(IndexTypes.Content, BooleanOperation.And);
                    var query= criteria.NodeTypeAlias("MyNodeType");

the field you need query will be isPublished

This link has a code that can help. For your needs, you would change the indexname and make a query for unpublished
