I just installed the latest almalinux on my raspberry pi cm4 using:
89773106f23407efb5258d7185d2005c6ed4f98f2ad23916948be573eb2efb95 AlmaLinux-8-RaspberryPi-latest.aarch64.raw.xz

Everything was seamless except for wifi.

There was no wifi driver file for a pi CM4 in /lib/firmware/brcm

I found a post by @geerlingguy in openwrt forums with the solution.

# cp /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-compute-module.txt

running the above command and rebooting resolved my issue.

It would seem that openwrt has implemented something similar into their upstream

Feel free to come back if it doesn't work on CM4.
