Disable WIFI and BT on Volumio + Pi3

Hello there ! I’m using Volumio + Pi3 + local official 7 touchscreen + touchscreen plugin, but i’m not using the Wifi and BT (using rj45). How could i disable Wifi and BT ?
i’ve try the blacklist solution :

/etc/modprobe.d/raspi-blacklist.conf and adding:

blacklist brcmfmac
blacklist brcmutil

but it interfer with the touchscreen, i’ve no more touch after this.

Network settings -> disable wireless
