Since you stated you vent to the outside adding humidly would be a challenge. I would suggest looking into anti-static floor mats near where you would work on the miners and a lot of grounding.
A facility where I worked at once had a ground bar installed in various places on the walls where you could touch to discharge any static before touching electronics. You might need to look into these type of options as the higher humidity solution sounds like it might be unavailable for you.

So based on this ESD is only a concern with human interaction? the miners sitting by themselves in this dry air are at not risk?
they are at risk if dust gathers inside the s-9
the fans can move dust and spark a bit of ESD.
been there done that.
I suggest taking s-9's apart and really cleaning dust out of them.
and 12% is low
you could have a few discharge mats at the entrance
Door to THE ROOM so you don't space out and ESD the gear.
