No windows update

Windows 10 Pro 20H2 and IE lock-down 210
When NO WINDOWS UPDATE is set it appears to disable the WINDOWS UPDATE service.
When the option is cleared the service is NOT restarted resulting in a windows error message when updates are requested.
Is there a fix in the works for this?

To disable Windows Updates, but then have a simple way to install when you want, you're better off following the methods found here:

My comment is based on using Secure Lockdown option:
SYSTEM LOCKDOWN tab NO WINDOWS UPDATE option.

Are you suggesting NOT to use this option?

I tried the options mentioned in the link.
The disable option in Policy settings work and set the appropriate registry entries.
All was OK until I enabled Lockdown and rebooted. I then disabled lockdown and rebooted.
I found updates enabled and the registry entries removed.
It appears the lockdown program is removing the needed registry entries.
Any suggestions.

Since there has been no further action on this issue, does it mean that support for the IE version is being reduced or ended?

You'll need to re-enable the setting prior to locking down the system again.
