rhsmcertd is the systemd service that performs the regular check-in on a connected/registered system. This has been always done, as seen eg in RHEL 9:

# grep -C 1 rhsm /usr/lib/systemd/system-preset/90-default.preset 
# https://bugzilla.redhat.com/show_bug.cgi?id=1271839
enable rhsmcertd.service

Hence, please add the same preset also in EL10. It looks like this is done in centos-release in older versions.
