For D4 players, as white, when is C4 NOT your second move?

I am 16 and expert among my age group at chess at zonal level when I won Gold medal.....
I always play d4 as white first since last 2 years!!
After d4, no matter what my opponent plays I play c4 except in 2 variations:
1) 1) d4 e5 (Englund Gambit)
Then I play e4 instead of c4 and it goes:
1) d4 e5 2) e4 exd4 (when Black captures) 3) Nf3 c5 4) b4 cxb4 5) Nxd4
With this, I have 53 such games in my lifetime till now, and I have won 41, drew 2 and lost 10.
2) 1) d4 c5 (Benoni Defense)
Then I play Nf3 instead of c4 and I have 318 games with cxd4 Nxd4, 252 games with d6, 181 games with b6 and 124 games with Nf6.

Let me give you away all my secrets:
1. d4 f5 2. Bg5
1. d4 d6 2. e4
1. d4 e5 2. dxe5
1. d4 c5 2. d5

@sluump There is also a whole set of opening with 2 Nc3, Zukertort, Colle, Torre. They are not trendy because they don't "press the issue" for white, meaning you can quickly get to a 0.0 evaluation, which delays the struggle, but they are solid and they have a bit of fire. One good point for white: those opening frustrate black, and are not familiar, so you have at least equal chances.

Nonetheless, many GMs have played that way, including at least one world champion.

The most common 1. d4 2. non-c4 opening I've seen is the London 🤮🤢

@FlamoToolz The London is just annoying to deal with...

People have been desperate to develop anti-London systems, but there simply isn't one...

Normally when I go d4 I just play the London to the point where it's a bad habit.
