Did you try to disable it via registry?
Please take a backup of the registry always that you are going to edit it >

Open the Run dialog box by pressing the Windows key + R key
Type Regedit and hit the Enter key.
When the Registry Editor opens, navigate to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\default\Settings\AllowSignInOptions.
In the right pane, double click on the DWORD entry named value set it to 0.
The above method will disable Windows Hello for all user accounts. If you want to re-enable
it, change the DWORD entry Value back to 1.
I hope this information has been useful, please let me know if you still need assistance.
