Was wondering about this error as well, looks like it's a benign warning
and can be ignored:
https://unix.stackexchange.com/questions/618869/debian-bullseye-firmware-for-i915

> rkl is apparently Rocket Lake, the codename for an Intel chipset that is
> supposed to be released in early 2021.
> <https://en.wikipedia.org/wiki/Rocket_Lake> So this is the Linux i915
> driver already getting support for hardware that is not released yet.
>
> The i915 driver covers a wide range of Intel iGPUs, including all the
> current ones and sometimes even near-future ones if they follow a design
> similar to their predecessors.
>
> The kernel modules like i915 include metadata indicating the firmware
> files they *may* need: the i915 module needs to declare the firmware
> files for all supported Intel iGPU versions this way.
>
> The update-initramfs tool is not smart enough to cross-check the hardware
> information to find out which of the various firmware files declared by the
> i915 driver are *actually needed* by your hardware, so it will simply
> attempt to include all of them into initramfs.
>
> Unless you have installed firmware files for *all* the Intel iGPU
> variants, you may get some nuisance messages from update-initramfs; but
> if they don't refer to the iGPU/chipset version you're actually using, you
> can simply ignore them.
