Small Cap MIS Issue

Sir I observed that some of the companies 

like adani transmission https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/GetQuote.jsp?symbol=ADANITRANS&illiquid=0&smeFlag=0&itpFlag=0

and Infibeam incorporation

https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/GetQuote.jsp?symbol=INFIBEAM&illiquid=0&smeFlag=0&itpFlag=0

{they are in NIFTY 500/ CNX500, sir..}

are not seen in the list of mis https://zerodha.com/margin-calculator/Equity/

     nor   in    bo&co https://zerodha.com/margin-calculator/BracketCover/​

So does that mean we wont be allowed here in zerodha to trade here???

these...i found are CNX500 companies..small cap around 6k-8k Cr.

i would like to know am i mistaken by thinking that we cannot trade here in zerodha with these companies in mind ?

or its like they are not there with mis support???

Please throw some light on this!!
