Probably the most realistic example I can think of is the Horizon series.
The first game, Horizon: Zero Dawn, features Alpy, a young woman from the Nora tribe in a post-apocalyptic version of America, set thousands of years after all life had gone extinct and re-evolved. The technology of the old world still costs, but is almost universally taken as being evil artifacts that caused the gods to destroy the world.
That’s a Focus, a piece if old world tech that basically acts like Siri and comes with an AR interface. Aloy found one as a kid and has used it for pretty much everything since. It helps her with hunting, tracking, fighting, simulating battle plans, etc. To pretty much everyone around her it looks like she has some sort of divine inspiration or knowledge of the world around her beyond what a person can see, but she is really just using any other tool. A handful of other people in this universe also use old world tech, but they seem to view the items as some sort of gift from gods, leaving Aloy unique as one of only a very small number of people to realize that technology, computers, various machines and such are just tools made by people.
Actually, Aloy seems to be bringing this to another series as well soon enough.
She is going to be added to a game called Genshin Impact in the 2.1 update as the first cross-over character. Genshin Impact has its own in-universe magic system based on manipulating the 7 elements of the world and every other playable character is distinctly powered by supernatural abilities. Aloy, however, is confirmed to not be using magic of any kind and her elemental abilities are going to be machinery based, as she will be equipped with various explosives and weapons that are coated in sub-zero cooling fluids from her home game.
