I have the Air75 from Nuphy and it is my current office board. It’s a very nice keyboard. I guess the new model uses QMK now, which is even nicer, so easy recommendation from me. I haven’t used their newer switches, but I have the tactiles from the old model and they feel quite nice.
If it’s a government type place, I can say that I can access the VIA site and connect to and update my keyboard. However, having a keyboard that allows a text file to be saved on it would probably be against policy, so I’m not sure that would even be a good workaround.
