I am able to assign an additional shortcut to zoom in and out using the System Settings > Keyboard > Universal Access > Magnifier Zoom In/Out
options, but regardless of what I set there, the shortcuts Meta+= and Meta+- still zoom in and out.
It's conflicting with a shortcut in another program.

I discovered a workaround via this answer to a related question.
First, use gsettings
to find the internal configuration setting we wish to change:
gsettings list-recursively | grep -i zoom
# ...
# org.pantheon.desktop.gala.keybindings zoom-out ['<Super>minus', '<Super>KP_Subtract']
# org.pantheon.desktop.gala.keybindings zoom-in ['<Super>plus', '<Super>KP_Add']
# ...
Then, change the individual setting as necessary. In my case:
gsettings set org.pantheon.desktop.gala.keybindings zoom-out "[]"
gsettings set org.pantheon.desktop.gala.keybindings zoom-in "[]"
Then you should be able to use the built in elementaryOS settings for the shortcut you want.
It seems like this may be a bug in ElementaryOS. https://github.com/elementary/switchboard-plug-keyboard/issues/31?_pjax=%23js-repo-pjax-container
