Is there any way to delete the ns1.linode.com to ns5.linode.com and make them my Cloudflare domain servers? The edit/remove is disabled.

Can you clarify why you would want to do this?

The reason that the NS records in the Linode DNS Manager cannot be edited is that the Linode DNS Manager controls the zone which our nameservers are serving for you. If you're using a 3rd party's nameservers to host your DNS, then the records you add to the Linode DNS Manager aren't relevant because requests for your domain are being handled by that 3rd party's nameservers. As such, the records that matter are the ones you set in their DNS control panel.

This can't be done through the Linode DNS Manager, it has to be done with whoever you have your domain registered through (GoDaddy, NameCheap, 1&1, Enom, Verisign, etc). There you can change your domain name's nameservers.

I am constantly fitting DDoS attacks and Cloudflare reroutes traffic and helps handle that. When I used their service, they say to change ns1 and ns2 to their name servers and delte the others.

I will change it with GoDaddy then.

It says the same here, btw:
