Is there anyway to disable collision on debris?

I have been trying for some time (not that much, about an hour…) to find a way to disable collision on only the debris. I tried using a delayer, but i have to disable it in an instant so that doesn’t work… If i try to use enable collision on my mesh it doesn’t destroy… and so on. Is there any way to do this? Thanks in advance!

Yes, the Large Chunk Threshold.

Thanks a lot!
