There wouldn't be a way to allow agent management without being an admin. Manage agents lives on the all settings page which you need admin rights to access. There's no singular permission for manage agents like there is for manage nodes, unfortunately. Could be a good feature request if it doesn't already exist as one.

"I am trying to allow our NOC to access "Manage Nodes" so they can reconnect passive agents" and "restart agents" but it doesn't look like there is a way to do that without giving them admin access."
Can you give them these permissions for SAM? Service Control Manager - Yes and Allow Service Actions Rights - Yes.
Then they could at least restart the Orion agent via the Service Control Manager. Of course if the agent isn't responding the Service Control Manager may not successfully pull back the running services to do that.
