The proposed update adds a BUILD_EXCLUSIVE_KERNEL directive to the dkms package. I have added a test build to https://launchpad.net/~smb/+archive/ubuntu/temp01/+packages and in a Focal VM which had the 5.4 and hwe-5.8 kernels installed, did an apt-get install zfs-dkms. This resulted in (relevant tail):
... DKMS: install completed. Building initial module for 5.8.0-25-generic Error! The /var/lib/dkms/zfs/0.8.3/5.8.0-25-generic/x86_64/dkms.conf for module zfs includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch. This indicates that it should not be built.
