Apple - Using Automator to batch crop with custom coordinates / measurements
Here is a way to achieve what you want with ImageMagick. Hopefully you’re comfortable using Terminal (and also use Homebrew to manage all your packages).
Either way, you must install ImageMagick so you can run convert command line in Terminal.

convert <input documents> <width>x<height>+<pos x>+<pos y> <output filepath>
