Trying to remove this module but no luck:

[use0@localhost ~]$ lsmod|grep rfkill
rfkill                 28672  1
[use0@localhost ~]$ sudo modprobe -r rfkill 
modprobe: FATAL: Module rfkill is in use.
[use0@localhost ~]$ sudo rmmod rfkill 
rmmod: ERROR: Module rfkill is in use

I removed the only dependency it had cfg80211 but rfkill is still not unloading.

Check following

systemctl status systemd-rfkill.socket

and

pidof wpa_supplicant

Then kill wpa_supplicant and stop the systemd-rfkill.socket and see of the usage count for rfkill is now 0.

wpa_supplicant is via a the systemd-rfkill.socket using the /dev/rfkill device to determine if wifi is enabled or not.

Thanks, I blacklisted the module in the mean time. The second command returns this error: pidof: invalid option -- i

It is supposed to be

pidof wpa_supplicant

use rmmod rfkill or use modeprobe -r rfkill

also check if it has dependencies by using modeprobe --show depends if there then rmmod that depends also.

else blacklist the module in (vi /etc/modeprobe.d/blacklist.conf install rfkill /bin/true )

hope it helps.....
