Disabling all of Defender is complex, but disabling automatic sample submission is easy. It's an option in the Security settings app, and you're even allowed to disable it during first time set up (or were, last I installed Windows 10).

It nags you once, but you can ask it to stop.

Besides, uploading unseen executable code and scanning photos are far from the same tech. They're very different things.

Every binary is executabale by default. Images are only subcategory. As malware, any file is potential threat. Also, I think disabling automatic sample submission does not disable hash upload, only full files.
