writing python script for keyframing crop region render in blender

I want to render a frame as a crop region, but I want to give the same frame a keyframe. It means that every keyframe renders a part of the image crop. For example, if I divide the image into 9 parts, that is, 9 crop regions. It means crop region as an animation. Can anyone help me in this field?? I want this to be done automatically. It means that when we open the project, the script will run automatically. Because I want to upload my project on a rendefarm and have it done there. Of course, I still don't know for sure whether the script should be uploaded separately or it can be attached to the file like a material, that is, as a package. And is this possible on renderfarm?please help me about the script and the renderfarm.thanks [1]: https://i.stack.imgur.com/AGj9Y.jpg
