    You need to stop and disable the DHCP client daemon.

    How exactly this is done depends on which version of Debian you’re using.

    On older versions, which I suspect you’re on, there is a dhcpcd service. Stop it with systemctl stop dhcpcd and disable it with systemctl disable dhcpcd.

    Newer versions or alternate configurations with NetworkManager or systemd-networkd will need those services reconfigured.
