No unfortunately not
[~] doas devctl detach pci0:0:20:3
devctl: Failed to detach pci0:0:20:3: Device not configured
[~] doas devctl set driver pci0:0:20:3 iwm
devctl: Failed to set pci0:0:20:3 driver to iwm: Device not configured
But then despite the 'device not configured' message pci0:0:20:3 does
seem to have attached itself to iwm0 again:

pciconf: Device not found

Not sure what to expect being in this state though, wlan0 is not present
[~]
[~] ifconfig wlan0
ifconfig: interface wlan0 does not exist
All kernel modules are still loaded:

7 1 0xffffffff82fea000 2e870 if_iwm.ko
39 1 0xffffffff85565000 880c8 if_iwlwifi.ko
Should I run: doas service netif restart ? (instead of powercycling)
