If you are just uninstalling CrowdStrike from a large group of devices, but not all devices, you should contact your Falcon Complete Team before proceeding as this requires adjustments to the Sensor Update policies.
Login to the CS Console
Click the burger icon in the upper left
Host setup and management > Manage endpoints > Host groups
Click Create new group > Name it, describe it, set the group type *depending on the situation Dynamic may not be the best choice and manually adding the devices via their hostname may be the best course
Click the Sensor Maintenance for the required OS(s) > click Assign policy
Once the policy applies to the devices you will be able to uninstall CS from the machines without the need for individual or bulk maintenance tokens
Put the CsUninstallTool.exe on the machines in question and run it via your RMM/Remote Access software to remotely uninstall CS or via Control Panel in Windows
