You may for clients that you are not sure about run a (wireless) packet capture and check the TLS version used:

I see occasionally issues after disabling TLS1.0/1.1, but those are in general old devices. Windows 10/11, versions of iOS/Android that are not older than let's say 5-8 years, should all support TLS1.2.
EDIT: I just
see this article that even states that ClearPass 6.9 and up have TLS1.0/1.1 disabled by default.

Subject: Disabling TLS 1.0/1.1
Hello,
We are disabling TLS 1.0/1.1 in our environment. This includes browsers, PC's, servers, etc. Will this affect my authentication in any way? We are using EAP-TLS for our authentication method. We have an authorization source for using Intune and an authentication source of AD for on-prem machines.
