NTLMv1 authentication

I know this is long overdue, but in pursuit.

I have identified our Radius servers (Windows Server 2019 NPS) as the main source of NTLMv1 authentications taking place. I want to disable NTLMv1 and LM, and enforce at least NTLMv2 within our Windows Environment.

The radius servers are used to provide network access, wired and wireless. How can we make sure that NTLMv1 is no longer used?
