Hide configuration on insertion

Hello

Do you know if it's possible to hide configurations without deleting them on Solidworks?  

For example, I have a piping element  that is scaled in diameters DN8, DN15 and DN20. We stopped ordering the DN15 and DN20 diameters because they were much too expensive. So I would like to hide the DN15 and DN20 configurations when inserting the component, but being already used in assemblies, I can't delete them. 

 

 

Thank you in advance for your help.
