Aspose.PDF is specialized to deal with PDF format and its conversion into different API formats. In case you need to apply some setting on PPTX file, you should use Aspose.Slides. So we are moving your inquiry to Aspose.Slides category where you will be further assisted accordingly.

@Sukhvinder,
The VBASigned property in PowerPoint documents cannot be changed. It is a read-only property.

Please note: Macros can be disabled in the PowerPoint application, but not for a specific PowerPoint document.

If you have a PowerPoint document with macros (PPTM file, for example), you can easy save it to a PPTX file. The result document will not contain macros.

using (var presentation = new Presentation("example.pptm"))
{
    presentation.Save("example.pptx", SaveFormat.Pptx);
}

You can also remove a specific macro from a PPTM file using the IVbaProject interface like this:

using (var presentation = new Presentation("example.pptm"))
{
    var firstModule = presentation.VbaProject.Modules[0];
    presentation.VbaProject.Modules.Remove(firstModule);

    presentation.Save("example_output.pptm", SaveFormat.Pptm);
}

To protect a presentation with a password, you should use the IProtectionManager interface like this:

using (var presentation = new Presentation("example.pptx"))
{
    presentation.ProtectionManager.Encrypt("my_password");
    presentation.Save("encrypted.pptx", SaveFormat.Pptx);
}
