How to change the account URI on acme.json?

I would like to use a specific account-id on letsencrypt since its whitelisted for ECDSA issuance and i want to try it on traefik. I tried to delete the privatekey, change its keytype, but it still is generating RSA. I did try creating a new one, and replacing the URI, which lands me on JWS verification errors. Is there a proper way I can accomplish this on traefik?

Can you please share what your configuration looks like?
