There's an exemption from Section 1201 for "Computer programs that control devices designed primarily for use by consumers for diagnosis, maintenance, or repair of the device or system".

I see in the "final rule" for 2024 (PDF) a section titled "11. Computer Programs—Repairs of Devices Designed Primarily for Use by Consumers", although it seems to indicate that nothing changed, as opposed to telling you what stayed the same.
