Disable the disable wifi key

Got Mint 19.2 (xfce) installed on a new Fusion III (14"). Seems to be working well. But for the second time this week wifi has suddenly cut off.

The problem survived rebooting. On another reboot I poked around in the bios, but there is no mention of wifi at all. I searched syslog and saw it saying that wifi was disabled. When we did Fn+F4 (which has a picture of an radio antenna), while watching syslog, it did wake wifi up. Strange, as tapping that key was something we tried before trying the reboot.

Q1: Is that Fn+F4 being handled by the bios, or by the linux kernel?

Q2: How do we stop that button doing anything? In other words, we couldn't think of any situation where we'd need a keyboard shortcut to toggle wifi.

(I found the rfkill command, which might be useful for troubleshooting/fixing next time. Also systemd-rfkill appears to be saying that still not working after a reboot is a feature not a bug :) But that suggests it is under kernel control, not bios control?)
