The php-7.2-gd package isn't available in Debian repositories (yet). But that doesn't matter, of course you can install it anyway. There's a great website named DEB.SURY.ORG that packages different software into Debian and Ubuntu (especially PHP packages).

First, download the key to the package source:

$ sudo curl -s https://packages.sury.org/php/apt.gpg | sudo apt-key add -

Then create a .list file in /etc/apt/sources.list.d/:

$ echo "deb https://packages.sury.org/php/ buster main" | sudo tee /etc/apt/sources.list.d/php.list

Then update and upgrade your distro:

$ sudo apt update -y && sudo apt dist-upgrade -y

Now you should be able to install the php7.2-gd package by running:

$ sudo apt install php7.2-gd
