Comment 1 for bug 1958433

A solution could also be to use a higher kernel version.

You can download the CentOS 7 cloud image, edit it and add kernel-lt (or kernel-ml) to it from elrepo-kernel (https://elrepo.org/tiki/HomePage).

After that, during deployment you will have to regenerate the initramfs with dracut and uninstall the "normal" kernel package (then it will use kernel-lt) using curtin commands. This is necessary because MaaS is only set up to regenerate the initramfs of the "kernel" package.
