Ok, I have a Kaby Lake so a bit more recent than Sky Lake.
Isn't it strange that update-initramfs tells me that some firmwares not corresponding to my processor generation could be missing? Doesn't the tool compare firmwares with actual hardware used?

W: Possible missing firmware /lib/firmware/i915/icl_dmc_ver1_07.bin for module i915
W: Possible missing firmware /lib/firmware/i915/tgl_dmc_ver2_04.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_huc_ver01_8_2893.bin for module i915

Actually, I had already installed firmware-misc-nonfree:

$ apt policy firmware-misc-nonfree
firmware-misc-nonfree:

My apt sources.list includes main, contrib and non-free.
I don't find the firmwares in Debian packages, only a bxt_huc old one:
$ apt-file search icl_dmc_ver
$ apt-file search tgl_dmc_ver
$ apt-file search bxt_huc_ver
firmware-misc-nonfree: /lib/firmware/i915/bxt_huc_ver01_07_1398.bin
