I am probably the least qualified person on the planet to answer this question but I will anyway and be probably dead wrong. Since shard blades are basically just dead spren (I think or they are just without investiture) then you might be able to if you had a living shardblade but I don't think you would be able to do it with non investiture techniques like dropping a mountain on the blade to try and shatter it. I probably just spouted a ton of crem dung so sorry.
