Can mutual fund be used as collateral for derivative trading

@Nithin, why aren’t funds being added to Zerodha’s pledging list when they have been in Clearing Corporation’s list for so long? Okay maybe initially, it got missed or something, but why is it not happening even after repeated requests!? Thought they might get added to the June list but that came out today & it’s not the case.
Again, correct me if I’m wrong or missing something here. If not, please do explain why Zerodha’s not doing what it probably should be doing here…
