How can we implement security for agent pools in Azure Devops

How can we restrict access to agent pools for certain groups in azure devops. As of now everyone has the access to agent pool . I need to manage that access. Any one please help

In the Azure DevOps agent pool, We can configure different permissions by updating user roles. Such as configure the agent permissions to restrict user or group access the agent pool.

Steps:

Open org setting-> agent pools->select agent pool->click the tab Security->remove the user or permission group

Result: the user or group member cannot access the agent pool.

Please refer the doc Security of agent pools and About security roles for more details.
