Steps to apply patch:

apt-get build-dep gnome-terminal
cd /usr/local/src
apt-get -b source gnome-terminal
cd gnome-terminal-3.44.0
wget https://gist.githubusercontent.com/huynp1999/24a8fd872ecbd1736cf80862984f4c47/raw/0a8ff2ea7d481f015b45bc6cea69480ced44cdcc/gnome_terminal_with_google.patch
cat gnome_terminal_with_google.patch | patch -p 1
meson _build -Dsearch_provider=false
ninja -C _build
ninja -C _build install

Kill all current gnome-terminal to use new patched version.
