Can I set Do Not Disturb status for an agent / make an agent unavailable for calls on a department, via the call centre?

Is it possible to toggle global Do Not Disturb on and off for an agent, via the API?

Alternatively, is it possible to toggle Do Not Disturb on and off for an agent in a specific department/call centre/office, via the API?

The only option I can see is to make the agent active or inactive, or remove them from the office entirely and re-add them... neither option is ideal.
