RWBuffer and Buffer in compute shaders when they binding with the same resource

hoping to get the point i am familiar with these two approaches:

Blocking the Game-Thread:

void AMyClass::Tick( float DeltaTime )
{
	ENQUEUE_RENDER_COMMAND( DoDispatch ) ( [this] ( FRHICommandListImmediate& RHICmdList )
	{
		// ... RHI Compute-Shader Dispatch Stuff ...
	} );

	FlushRenderingCommands();
}

Not blocking the Game-Thread:

FThreadSafeBool bAsyncWorking = false;

void AMyClass::Tick( float DeltaTime )
{
	if( bAsyncWorking == false )
	{
		bAsyncWorking = true;

		ENQUEUE_RENDER_COMMAND( DoDispatch ) ( [this] ( FRHICommandListImmediate& RHICmdList )
		{
			// ... RHI Compute-Shader Dispatch Stuff ...

			bAsyncWorking = false;
		} );
	}
}

Though i am not sure about the benefits of the RDG Render-Dependency-Graph in regards to basic compute-shader dispatching. (for UE5 i just adapted some code within the rendering-pipeline to match the RDG scheme).
@agreatworld would you recommend to use the RDG-system for Compute-Shader dispatches when resources depend on each other?
