Can I set up a login banner on the NAD equipment during ISE's setup

[CCC3]

When performing TACACS authentication through ISE,

If the NAD equipment succeeds in TACACS authentication, can I get the login banner to float?

If you can, can you let the TACACS information (user username, ip, etc.) pop up there?

Don't think you can send a banner from ISE after authentication. There are multiple banner options locally at least in Cisco devices but they are pretty much static.

You can not set banner in ISE when user success or failed but you can config TACACS to show unique Username/Password prompt 
this will make you sure that user use tacacs to access device.

you can also use below in device

aaa authentication banner delimiter-string delimiter
aaa authentication fail-message delimiter-string delimiter
