VB.NET - How to convert IEnumerable to DataTable in VB.Net without using looping

I used this code
Dim orgCustomers = From rw In ds.Tables(0).AsEnumerable()
                                        Group rw By grpId = rw.Field(Of String)("CustomerID") Into Group
                                        Where (Group.Count() = 1 Or Group.Count > 1)
                                        Select (Function(g) g.Key)

how to convert orgCustomers to DataTable.
I tried this one also, (not working)
Dim ttd As DataTable = chtView.AsEnumerable()
this also, (not working)
Dim tb As DataTable = CType(orgCustomers, DataTable)

but i cannot use looping statements because it makes slow process

The LINQ query you've got here to extract records from the DataTable is slower than whatever loop you intend to run to recreate a new DataTable from it.    I'd rethink my whole strategy on this.

ok, i will thanks

Any idea for how to remove duplicate rows based on one column from DataSet.

Without loop i can't
So i used like this.
Dim orgCustomers1 = (From rw In ds.Tables(0).AsEnumerable()
                                                        Group rw By grpId = rw.Field(Of String)("CustomerID") Into Group
                                                        Where (Group.Count > 1)
                                                        Select Group)
                                   

                                    'HERE REMOVING DUPLICATE

                                    For Each drr1() As DataRow In orgCustomers1

                                        If drr1.Length > 1 Then

                                            ds.Tables(0).Rows.Remove(drr1(drr1.Length - 1))

                                        End If
                                    Next
