De-registering Metadata to modify URL

[arthurgousset]

Copying a question asked by Robert | Virtual Hive on Discord so we can answer in detail and refer back here for future reference:

Have to catch up on this one. What is the best practice to de-register metadata? (re-registering a different URL is not an option for us in the testnet right now) Will attestations also be directed to our validator when the gist will be deleted?

[In reply to Discord message below]
x-posting from stake-off since this question is only relevant for attestation

Is there a way to deregister-metadata?
The wrong URL got registered as the metadata
Sending another registerMetadata transaction does not seem to override the current one

Copying answer from Discord (for future reference):

Hey Robert | Virtual Hive, just wanted to quick follow up on your question.

What is the best practice to de-register metadata?

So I can help you best, would you be able to add more context on the problem you have with your metadata?

Will attestations also be directed to our validator when the gist will be deleted?

If I understand correctly, no. Attestation requests will look up the attestation service URL registered in the file hosted in the gist.

Thanks!
