Hi Basith,
At present , we do not have the support to convert the PDF document to PDF/A conformance level. Currently , we can create conformance formats while creating a new PDF document.
Please refer to the following code snippet:
// Create a new instance of PdfDocument class with conformance level.

PdfDocument document = new PdfDocument(PdfConformanceLevel.Pdf_A1B);

// Add a page to the document.
PdfPage page = document.Pages.Add();
You can refer the following assemblies into your project:

Please let us know if you need any further assistance .
