Can you install firmware from a newer Canon DSLR to add features to an older one?

I have an older Canon DSLR and noticed that newer models add features like 5-shot bracketing instead of 3, or different autofocus/custom options, even when the cameras seem otherwise similar on paper. That makes me wonder whether some of these differences are software rather than hardware.
Is it possible to load firmware from a newer Canon model onto an older one to unlock those features, similar to flashing a different BIOS on a GPU? Or is that likely to brick the camera? If cross-flashing is unsafe, are there any safer third-party firmware options that can add features without replacing the original camera firmware?

In some degree you are right about some options which depend of the software. As one example I can give you 77D and 70D. As you can suppose first is new model, which have option to set maximum Auto ISO, but not minimum shutter speed as it is possible on the old model (when on Auto ISO). (comments on this answer)
But some things depend on the hardware and this is not only the sensor but also the processor, heat balance, focusing system, etc.
I am afraid your try to install Canon firmware from other model (even if its successful as process) may brick the camera.
But you can try Magic Lantern. When download this software be careful about the firmware level your camera must have. Here is for example one firmware for 500D
The good thing about ML is you do not touch the original firmware, you run this software from SD card and you can easy switch to the standard firmware by removing the card and restart the camera.

In general, no: installing firmware from a different camera model is very likely to fail or brick the camera.
Even when two cameras look similar, firmware is tied closely to the exact hardware: sensor interface, processor, autofocus system, display layout, switches, power management, and other internal components. Small hardware differences can make another model’s firmware unusable or even dangerous.
You’re right that some camera features are software-controlled, but that does not mean firmware is interchangeable between models. Manufacturers also intentionally limit or change features across model lines.
If you want extra features on some Canon DSLRs, the safer route is to look at Magic Lantern, where available. It is designed for specific supported models and firmware versions, and it does not replace Canon firmware in the same way as cross-flashing another model’s firmware. You still need to follow compatibility instructions carefully.
So the practical answer is:
- Don’t try firmware from a newer/different Canon body.
- Use only official firmware for your exact model.
- If supported, consider Magic Lantern for added features.
