You need the debian-live with non-free firmware included: https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.2.0-live+nonfree/amd64/bt-hybrid/ and whichever desktop you want. I would very strongly suggest NOT to use debian-live images to install if you're not sure - as another user has found, they can install large amounts of extra software and would, instead, suggest installing using the non-free firmware netinst or the DVD: https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.2.0+nonfree/amd64/iso-cd/firmware-11.2.0-amd64-netinst.iso or https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.2.0+nonfree/amd64/iso-dvd/firmware-11.2.0-amd64-DVD-1.iso then work through. The files you need are almost certainly in either firmware-linux-nonfree or firmware-misc-nonfree: it's probably worth installing those at some point to make sure.
