This is very much not an option on most embedded devices. They allow one key to be burned once.
IIRC, a certain Marvell SoC datasheet says multiple key slots are supported, but the boot ROM only supports reading the first entry (so really, only one key is supported).

Unless it becomes a law, and the hardware makers adapt.
My Google Pixel allows adding custom keys, which GrapheneOS uses. So I guess that's technically feasible?
