Using GTC For inner Auth in a wired connection

Help
1

Hello, I have a wired connection on a network that requires authentification, the auth is done using:
802.1x security –> TTLS –> GTC

However, as inner authentification KDE does not have the GTC option. How can I force it to show?

I could set it to GTC on gnome but not here so I dont think it’s an hardware issue.

Thanks for the help !
