How to Freeze JSF Radio Buttons

How to Freeze JSF Radio Buttons

i have the following jsf code:
<h:selectOneRadio value="#{ref.arrive.boardingInformation}">
<f:selectItems
value="#{newMessage.boardingInformationSelectItemList}" />
</h:selectOneRadio>
Is it possible to freeze this kind of selectradiobutton in that way, that
my user can´t change the value?
This radiobuttons are only for reading and not for writing or changing.
Thanks for helping me !
