BTW., it's also questionable whether the owner is *aware* of the fact that NX is not available: what if some kernel debug option cleared the NX flag, unintended, or there's some serious firmware bug?
However unlikely those situations might be, I think unconditionally warning about NX not available is a very 2023 thing to do.
Thanks,
