How to check for interface inheritance when looping through a list?

I have a Blazor server-side app where I use DynamicComponent on a page to create and add components at runtime. To do this I have the following:

A set of interfaces:

public interface IGetData{    Task GetDataAsync(string condition);}public interface IGetDataA : IGetData{    Task GetDataAsync(CriteriaA criteria);}public interface IGetDataB : IGetData{    Task GetDataAsync(CriteriaB criteria);}

And then in the page (after creating the components):

public async Task RefreshAsync(){    var itemsA = items.Where(x => x.Ref.Instance is IGetDataA)        .Select(x => x.Ref.Instance)        .Cast<IGetDataA>();    await Parallel.ForEachAsync(itemsA, async (item, token) =>    {        await item.GetDataAsync(criteriaA);    });    var itemsB = items.Where(x => x.Ref.Instance is IGetDataB)        .Select(x => x.Ref.Instance)        .Cast<IGetDataB>();    await Parallel.ForEachAsync(itemsB, async (item, token) =>    {        await item.GetDataAsync(criteriaB);    });}

Is it possible to unify the above into just one cast and one loop?

UPDATE

I've made changes to improve the code. I've simplified the interfaces as follows:

public interface IGetData<T> {    Task GetDataAsync(string condition);    Task GetDataAsync(T data);}

And the code:

bool IsGetData(object o) => o.GetType().GetInterfaces().Any(x =>    x.IsGenericType &&    x.GetGenericTypeDefinition() == typeof(IGetData<>));var list = items.Where(x => IsGetData(x.Ref.Instance))    .Select(x => x.Ref.Instance);await Parallel.ForEachAsync(list, async (item, token) =>{    if (item is ItemA)        await (item as ItemA).GetDataAsync(criteriaA);    else if (item is ItemB)        await (item as ItemB).GetDataAsync(criteriaB);});

Now I have an extra helper method and also i need to use is and as. Is there a way to simplify the code further?
