Open GPEDIT.MSC and navigate to Computer Configuration/Administrative Templates/Windows Components/Data Collection and Preview Builds: Allow Telemetry: Disabled
I believe the relevant setting is called "Allow Diagnostic Data" in Windows 11 Group Policy Editor (at least it is in Windows 11 24H2 IoT LTSC and Windows 11 24H2 Enterprise).
