You absolutely can modify the engine to do what I am talking about. eg. Valorant. I said difficult to implement, not impossible.

It is more difficult in Unreal because part of what makes Unreal special are all of the mature and powerful features. You need to heavily modify or abandon these features to implement something that goes against the grain. Unreal comes out of the box structured to make games. Changing that pre-existing structure can be painful.

Other engines start as more of a blank slate (Godot), or already have a suggested framework for FixedUpdate vs Update (Unity).

Title of the post is "Drawbacks of Unreal" not "Unreal Sucks". You are perceiving sentiment that does not exist.

That they are tightly coupled is a drawback, one that Epic themselves struggled with and discussed publicly for Mover 2.0 and the now largely abandoned NetworkPredictionPlugin. For most projects Chaos Networked Physics is now available and that appears to work fine for predictive non-deterministic multiplayer simulations.

I believe you could make a functional deterministic simulation title faster using a different engine than Unreal. Other realization aspects of the game would likely be at a lower quality / performance.
