A workaround might be to enable NT1 protocol as default.

In Win8.x/Win10 NT1 is deactivated and must be activated via PowerShell.
> Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol

now you can disable SMB2/3
> sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
> sc.exe config mrxsmb20 start= disabled

According to the partner/customer this does not helped in the specific environment - probably it might help in others.
