Hi Mr Andrey, 
 
Thank you for your update. 
 
We can remove the page from existing PDF document by using RemoveAt method from PdfLoadedPageCollection class. We do not have support for removing everything drawn from the page. As a workaround, we can remove the page and insert a new page based on that page index. We have attached the sample and output document for your reference. Kindly please try the sample on your end and let us know the result.

Hi Mr Andrey, 
 
Thank you for your update. 
 
As we said earlier, we can remove the page from existing PDF document by using RemoveAt method only from PdfLoadedPageCollection class. We do not have removeAt method from PdfDocumentPageCollection class, here you can insert the empty page from pdfdocument page collection. We request you to use the removeAt method from loaded page collection.
