How to force traefik to renovate LE certs?

I changed keyType on my acme config to use EC256 instead of the default RSA 4096 one. I expected traefik to fetch a new certificate now that the config is changed after a restart but it still serves the old one. Is there a way to force a certificate update?

Removing the acme.json file isn't an option since that would mean that every other site that uses other certs will stop working until traefik refreshes all the certs.
