@AnonymousPerson The answer is the same as when you asked this question in November last year.
Yes it is possible, log into the hub’s web interface on 192.168.0.1, (if you have never done this before then it will be the default password on the sticker on the base of the hub), find the WiFI section and untick the boxes for both the 2.4 GHz and 5GHz bands. Save and exit and that should be it.
