I haven't done the data dive that I do before composing a hardware build, as I'm letting things stabilize for a year or so before I go in that direction.
However, if it's not on the QVL, all that means is that it hasn't been tested and verified to function properly in a particular configuration.
The absence from the QVL, on its own, does not mean that it will not work in your application--it just means that it's your risk to try it, and you should anticipate that it will not, and have a "Plan-B" in place ahead of time.
