Asking politely will be as effective as prayer (and if that's good for you, then by all means). Asking impolitely will be less effective. Unfortunately that's about the sum total of your options. VM appear to have a Hub 5 shortage, usually the case when any new hub gets rolled out, doubly so at the moment I suspect because they need the manufacturer to be churning out Hub 5x models for the XGS-PON trial areas.
If you have to wait long enough, it's even possible that you might get a Hub 5 that supports Wifi 6e (the current Hub 5 is just vanilla Wifi6). But that's unannounced, and probably a couple of years away yet.
