C# Dynamically determine class properties based on configuration for comparison

I have a configuration defined for duplicate check on each property in my model below

public class ConfigurationModel
{
    public GroupValue Value1 { get; set; }
    public GroupValue Value2 { get; set; }
    public GroupValue Value3 { get; set; }
    public GroupValue Value4 { get; set; }
    public GroupValue Value5 { get; set; }
}
public class GroupValue
{
    public bool duplicateCheck { get; set; }
}

I have the real class which has all the properties defined like Value1, Value2 etc, which we will call it as OrderModel

public class OrderModel
{
    public string Value1 { get; set; }
    public string Value2 { get; set; }
    public string Value3 { get; set; }
    public string Value4 { get; set; }
    public string Value5 { get; set; }
}

Now I want to include only those properties for duplicate check which have the respective flag in configuration set to true. Example

bool CheckDuplicate(OrderModel newOrder)
{
OrderModel existingOrder = //GetfromDB;
//Compare only those properties in newOrder and existingOrder which have duplicate check set to true in ConfigurationModel
}

Using reflection to getproperties by string name and then compare is what I had in mind, But wanted to check the best way to do it, keeping performance in mind as well. Any help would be greatly appreciated.
