I confirm that your tip does work and effectively solves the issue of secure NTP.

HKLM\SYSTEM\CurrentControlSet\Services\w32time\TimeProviders\NtpClient/ SignatureAuthAllowed

Change from 1 to 0.

After distributing this registry setting via GPO, the Windows clients are synchronizing correctly.

Thank you!
