Is there a quantized version of MOND where the increased acceleration is because a quantized unit of gravity will exert force across distances that would otherwise suggest that that the force would be less than a "g quanta" or because maybe quantization "ceilings" more than floors at very large distances? If gravity does have some kind of particle or fundamental quantization like a photon, and basically still exerts at huge or "infinite" distance, does it make sense that it's more likely there's some kind quantization floor or maybe quantization bands or something? Or is it thought that quantization of gravity imposes a limit on distance for the exertion of gravitational attraction? (Or is it thought that that with quantized gravity that what's happening is a decreased rate of "gravitons" interacting between the objects?)

Anyway, a bit clueless about this, just curious what gravitons are supposed to mean for either theory (MOND, LCDM, etc.).
