Can't switch ublue using bootc

I followed the documentation from google search. But it gives error.

sudo bootc switch --enforce-container-sigpolicy ghcr.io/ublue-os/bluefin-dx:stable
ERROR Switching: Pulling: Preparing import: Fetching manifest: containers-policy.json specifies a default of `insecureAcceptAnything`; refusing usage

Any solution? I am using Fedora Silverblue 41.

Fedora doesn’t have our key so try it without the enforcing signature flag first, and then after you’ve booted into the new image switch to the signed image.
