Way to reset DNS settings?

is there a way to reset my DNS settings? i kinda messed it up

Short of removing the entire domain and setting it up from scratch, not really.

Even then, it wouldn’t do any good if nameservers have been transferred.

If the old provider offers zonefile access it adds another way to upload records in bulk, but this is provider dependant and Cloudflare’s zone file import is sloppy at best.
