If you're looking for a one line command, you can use this command:

kubectl patch my-cronjob -p '{"spec":{"schedule": "42 11 * * *"}}

Hey @Lina, You can use the keyword patch to update only the selected fields of resource.

$patch -h                   
Update field(s) of a resource using strategic merge patch, a JSON merge patch, or a JSON patch.           

JSON and YAML formats are accepted.

What's the -p for?
-p --> --patch
You also need to mentionthe object type that you want to patch, like:

kubectl patch cronjob <cron-job-name> -p '{"spec": {"schedule": "* * * * *"}'
