I responded to an internal thread on 2020-Sept-12:
For ISE, I tried ISE 3.0 FCS candidate with Windows Servers 2019 updated to the latest Windows updates and not getting any of the windows events described in the MS article above. I also tried setting FullSecureChannelProtection to the value of 1 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters and ISE 3.0 still able to authenticate.
Thus, we should be good to claim that ISE working ok with DC enforcing the use of Netlogon secure channel.
