The NMP and GIFA are structural flooring, tongue and groove construction boards, and as long as there is adequate joist spacing, yes, that’s a finished substrate. They’re inert, and won’t change shape at all. Although can be difficult to source because it’s still not used enough.
There are NO anti deflection products as such.
Some help, but none are designed for that purpose, only lateral movement.
The deflection should be removed by correctly prepping the substrate.
For example, adding noggins between joists, and renewing what goes on the joist.
That’s when options start to creep in.
