Why is F&O activation mandatory for pledging stocks in Zerodha?

Why F&O needs to be activated in Zerodha for pledging stocks? Like I don’t trade F&O at all but I want margin only for equity Intraday but it’s not possible without activating the F&O segment. Isn’t it possible to seperate the pledging for Equity Intraday and F&O?

Almost all trade fno primarily by pledging stocks, so from the beginning we have kept our process that way. Will see if we can do some changes to it in coming days but for now it stays.
