There was some discussion on the GitHub issues about workarounds to disable it, even though it is baked in.

This worked as a mitigation on distros with the module compiled into the kernel: https://gist.github.com/m3nu/c19269ef4fd6fa53b03eb388f77464d...

Basically: sudo grubby --update-kernel=ALL --args=initcall_blacklist=algif_aead_init

sudo reboot

F44 is safe as the kernel is greater than 6.18.22

For compiled-in kernels you can also work around it without rebooting via apparmor, seccomp or SELinux at the least, there may be eBPF or other methods too.
