You can play Spielmann-Indian (1.d4 Nf6 2.Nf3 c5). Chessable has a complete course:
Huy's Original Repertoire: Spielmann-Indian by BanhGiaHuy.
The mainline is 1.d4 Nf6 2.Nf3 c5 3.d5 b5.
Another possibility is 2…g6. If white plays 3.c4 then you can go for Maroczy Bind or Delayed Benoni.
There is a Gabuzyan example here: https://www.chessbomb.com/arena/2021-avagyan-memorial/09-Paravyan_David-Gabuzyan_Hovhannes
There are some comments about that game here: https://www.chesspublishing.com/content/9/index.htm (King’s Indian Update September 2021)
I also play Modern Benoni and answer 2.Nf3 with c5.
1) In case that white plays 3.d5 then I play 3…e6 and in most cases the game will continue with 4.c4 d6 5.Nc3 exd5 6.cxd5
2) If white plays the popular 3.c3 then I play 3…cxd4. After 4.cxd4 I continue with g6, Bg7, 0-0,
a6, b5, d6 and Nbd7. I have great success with this setup.
3) If white plays 3.e3 then I continue with g6, Bg7 and 0-0. If white then plays plays c4 (e3, d4, c4 setup) then a good version of reversed Tarrasch (black plays cxd4 after castling and d5 if white plays exd4) is possible (more about that in Chessmood’s English course, section 6).
A good delayed Benoni (white plays d4-d5 but wastes a tempo if he plays e3-e4) is also possible.
If white continues with with c3 after 3.e3 then I play double fianchetto.
