grease that totally eliminates noise is too thick, and will cause excessive drag.
What type of bike is yours? MTB? Road? Comfort?
what brand/model hubs?
It is a road bike.
I am trying to grasp if it is time to replace the bearings on my bike. Is there a way to tell when that noise from the bearings is much enough to indicate the need of change of them? Considering they are cartridge bearings, is there a risk of damaging the wheels while using it till the man at my local LBS gets back?

IF that type, you really aren't going to hurt them by riding until they definitely "tell you". they're bad.
The other type needs "normal maintenance". Damage can result to the cone & cup(hub)
What is the brand & model hub?
That may give us the info to Intelligently advise you.
Well said (you see how far my knowledge on this goes...). They are cartridge bearings on Axis wheels of a Specialized Alez Sport 2021 bike.
When do they "tell you" they 're bad? So far I feel something like a murmuring/vibration on the bars while holding the front wheel up and spinning it, but it runs smooth.
