How do I deepen flatlands in Minecraft?

Hello everyone reading this and thank you in advance to all who answer.

So I wanted to create a flat world and build something underground. Unfortunately, that was not possible because the world is only 4 deep and building earth up would take too long. I looked at Dan if I could somehow lower the map but I just don't think this setting could someone explain to me how I can make the map lower? So via command or in the settings. (I have the new Minecraft version for the Ps4)

Track mania or what's going on?

Oops. A game… And I was just thinking that someone wanted to place a large excavator order…

No in Minecraft I should probably have written it down

Can you set everything right there?
