How to dynamically change the ConverterParameter property (or any) of a MultiBinding resource (or any other) at run time?

I am new to wpf and xaml. I find solutions to most problems (in other languages) by searching here or where I am, and it made me go crazy. I searched a lot on google and looked through many forums, but it seems that this time I met a real problem!

I have the following code in Window.Resources:

<my:NameConverter x:Key="NameConverter"/>

<MultiBinding x:Key="CustomerFullNameBinding" 
              Converter="{StaticResource NameConverter}"
              ConverterParameter="LastNameFirst">
     <Binding Path="FirstName"  />
     <Binding Path="MiddleName" />
     <Binding Path="LastName" />
</MultiBinding>

The NameConverter class returns the full name, combining the individual parts of the name. The return value is based on the ConverterParameter value , which can be one of the following: FirstNameFirst, LastNameFirst, OnlyFirstName, OnlyLastName, Initials (there are a few more, but for simplicity do not consider them)

. :

<TextBlock Text="{DynamicResource CustomerFullNameBinding}"/>

, CustomerFullNameBinding 20 (, abovw), . (.. , CustomerFullNameBinding, ConverterParameter = "LastNameFirst", 20 .)

: "", ConverterParameter?, , . , , , :

 <MultiBinding x:Key="CustomerFullNameBinding_FirstNameFirst" 
               Converter="..." ConverterParameter="FirstNameFirst">
      ......
 </MultiBinding>
 <MultiBinding x:Key="CustomerFullNameBinding_LastNameFirst" 
               Converter="..." ConverterParameter="LastNameFirst">
      ......
 </MultiBinding>
 <MultiBinding x:Key="CustomerFullNameBinding_OnlyFirstName" 
               Converter="..." ConverterParameter="OnlyFirstName">
      ......
 </MultiBinding>

 ... and so on ...
