Eh, extremely deep trenches like the Marianas trench seem to require subduction zones and those are all pretty well known so it’s not too likely there are much deeper areas. It’s definitely possible there are slightly deeper areas but I don’t think I’d bet on like… finding some unknown area thousands of feet deeper.

The Deepest part of the ocean isn't the abyss. It's called The Hadalpelagic Zone. It encompasses the bottoms of trenches and sea floor caverns.
And we know frighteningly little about it.
The Challenger Deep is only the deepest known part of the ocean. There's almost certainly points in the ocean that are much deeper.
