I've checked the DKMS source package in Ubuntu and it just makes the
signature checking not enforced anymore, which is violating Secure
Boot standards actually.

Usually the kernel signing stuff is done at kernel build time and only
exactly those modules produced in the build can be loaded because the
key should be generated at build time and through away when the build
is finished. In theory dkms kernel modules can hardly meet the
requirements of Secure Boot because kernel is usually treated as part
of the boot chain where signature verification is required.
