Lock the Resource Schedule

Hi Everyone,
We are looking for something that can somehow locked the schedule on a particular resource.
Say for today we have 3 jobs that scheduled on that resource, then we don’t want anymore jobs to be inserted on that resource schedule.
I know that we can lock the schedule on the job but we want to lock the resource level.
Is there something like this that I am missing? or can this be achieve somehow through some BPM’s or customization?
Thank you.

Resource calendar can add an exception after x hour probably

You could use the Resource Scheduling Board to see what Jobs are scheduled and lock those operations.
