Turn off Find My iPhone from iCloud

If you’re not using a device, you can temporarily remove it from your account so it doesn’t show up in your Devices list. When the device goes online again, it reappears in the list if it has Activation Lock turned on (for an iPhone, iPad, iPod touch, Mac or Apple Watch) or is paired with your iOS or iPadOS device (for AirPods or a Beats product).

Turn off device or put the AirPods in their case. The device must be offline before you can remove it from the Devices list.
In Find My iPhone on iCloud.com, click All Devices and then select the device you want to remove.
If you don’t see All Devices, it’s because you’ve already selected a device. Click the name of the current device in the center of the toolbar to see the Devices list and then select a new device.
Click Remove from Account.

Note: You can also remove your iPhone, iPad, iPod touch or Mac by turning off iCloud completely on that device. Turning off iCloud turns off all iCloud features on the device.
