I grew up in the evangelical church, and I've never heard anything of the sort. I think you should maybe do a bit more research on what people believe than some guy going "hey, I hear this is what evangelical's believe".
For context from last thread:
The existence of the New Covenant does not mean the one that existed in the old testament is no longer valid, which is confirmed by genesis 17:7, which says the Covenant between God and the jews shall be everlasting.
