Ubuntu 24.04 LTS - UEFI Microsoft CA 2023 [closed]

I'm currently using Ubuntu 24.04 LTS with SecureBoot enabled.

I'm wondering which certificate shim is currently using. Is it the 2021 or 2023 certificate? Both?

The following command shows me the 2021 certificate:

sbverify --list /boot/efi/EFI/ubuntu/shimx64.efi

I have already searched for a shim package, unfortunately I cannot find an updated version with MS CA 2023 cert
