Disable Network-Manager to use isc-dhcp-client

[Fernando Lima]

Hello.
I'm trying to disable Network-Manager to only use isc-dhcp-client and control network settings via /etc/network/interfaces
But whenever I disable or delete Network-Manger and install isc-dhcp-client. After restarting the device it loses communication with the network.
Follow the data:
Device: nanopi core
Armbian Bookworm
Kernel 6.6.28

How I have done the procedure:
apt purge network-manager
apt install isc-dhcp-client
echo "extraargs=net.ifnames=0" >> /boot/armbianEnv.txt
cat << EOF > /etc/network/interfaces
auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp
EOF
