I want to disable monitor mode for the interal wlan0 card of the pi. If you want to do that too and use wlan1 as mon0 do:
sed -i 's/phy0/phy1/g' /usr/bin/pwnlib
If you want wlan0 and wlan1 in monitor mode and want to use wlan1 as pwnagotchi device, use this ps did didn't work for me but above example
sudo su
rm /etc/network/interfaces.d/wlan1-cfg
