The way that NvPCRs are initialized and anchored in systemd is changing, and to support this, the UKI needs to include signed PCR policies that can authorize NvPCR initialization in early boot. This is enabled with a new --sign-nvpcr-init option for ukify. This adds a new "SignNvPCRInit=" option to control this. The default is "auto" which will turn on this option if PCR signing is enabled and ukify is new enough. The corresponding systemd PR is systemd/systemd#42796
