Add OBV as parameter to RSI

Since RSI takes close as parameter and time period (which is customizable),

Is there a way I can use “OBV” instead of “close” as the first parameter and time frame as a normal second parameter?

I want to achieve this on Zerodha Kite, an equivalent to this on Amibroker is “RSIa(OBV(), 20)”.

You can only change TIme Period on Kite, changing Field isn’t possible.

Okay. Thanks for answering : )
Any suggestion for what other tool can I use for achieving this?
