Not able to set "EnableExternalImages = true" for AspNetCore.Reporting 2.1.0

I am using reporting package - AspNetCore.Reporting 2.1.0 (https://www.nuget.org/packages/AspNetCore.Reporting) to generate the PDF report using RDLC.
But don't know how to set - "EnableExternalImages = true" for the local report.

It would be great if someone has an example code for RDLC in DotNETCore
