So that the changes take effect
I have updated to 14.1.1 and locked those domains, disabled the service mentioned by ParkerPerry. For now, it looks good, but in future updates, it can be restricted to disabling the mdm service or even disabling the ability to block the mdm host on the OS level. We need some time to pass to see if everything is working as expected.
