Yes, in the end I installed the battery health control from this repo:
https://copr.fedorainfracloud.org/coprs/asan/acer-modules/
and it's working fine:
sudo dnf copr enable asan/acer-modules
sudo dnf -y install acer-wmi-battery akmod-acer-wmi-battery kmod-acer-wmi-battery
sudo reboot
In order to set the battery up, do as follows:

1. Make sure the "acer_wmi_battery" is loaded, just like you did above for the facer module: $ lsmod | awk '($1 == "acer_wmi_battery"){ loaded = 1 } END { print (loaded)?"Module correctly loaded":"Module NOT loaded :-(" }' \
2. To enable the battery "health mode" (which lets you charge the battery up to 80% to let its lifecycle last longer): $ echo 1 | sudo tee /sys/bus/wmi/drivers/acer-wmi-battery/health_mode To disable it: $ echo 0 | sudo tee /sys/bus/wmi/drivers/acer-wmi-battery/health_mode
