How to get rid of teq10 tun10@NONE gre0@NONE and cie.

Hi, I'm trying to get rid of teq10 tun10@NONE gre0@NONE gretap0@NONE erspan0@NONE ip6_vti0@NONE sit0@NONE ip6tn10@NONE ip6gre0@NONE that shows up in 'ip link'. I tried looking into /etc/systemd/network and /usr/lib/systemd/network but nothing.

My bet is I have to change my kernel config or write a script for boot that deletes the devices...

Thanks
