Spatial data with OData

I've web api project using .net 5, EF core 5, SqlServer.NetTopologySuite, OData, Newtonsoft Json

I've normal api controller and odata-enabled controller as below:

public IServiceProvider ConfigureServices(IServiceCollection services)
          .AddNewtonsoftJson(options =>
             options.SerializerSettings.Converters.Add(new NetTopologySuite.IO.Converters.GeometryConverter());
             options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

The web api controller successfully convert Point object to JSON as I'm using Newtonsoft with the NTS converter, but odata has its own json serializer with no custom converters so I got an endless loop: enter image description here

Any thoughts?
