I have a private domain .edu.co in Colombia which is only managed by cointernet.com.co and is not transferable to other servers, it can only be redirected with NS. Here is my problem, I bought the WordPress hosting offered by Godaddy but at the time of configuring the DNS appear 2 NS and 1 SOA that does not allow me to remove or modify (ns29.domaincontrol.com - ns30.domaincontrol.com - Primary nameserver: ns29 .domaincontrol.com) which are the ones created by default. I need help to eliminate them.
In the image you can see that in those 3 is not the pencil to edit and the whole page does not appear a button to change the NS by default
I guess I'm a little confused by your question - I was able to see that teslaeducativo.edu.co
is pointed to ns30.domaincontrol.com and ns29.domaincontrol.com - therefore you shouldn't need to add (in either the domain settings or the dns record) the ns1.teslaeducativo.edu.co and ns2.teslaeducativo.edu.co
If you are trying to "mask" the godaddy servers and just use ns1. and ns2. instead - here is a help article on that https://www.godaddy.com/help/add-my-own-host-names-as-nameservers-12320
