How to remove Consul Connect?

We’re using Consul 1.12.0. At one point we tested using Ingress Gateways with Consul Connect but ran into some weird edge cases where TCP connections were getting closed by the proxy. We changed our architecture and no long use any piece of Consul Connect. How do we get rid of it? It generates errors which are alarming (can’t renew certs, can’t connect to Vault, etc.).

We’ve tried changing the connect stanza to:

connect = {
    enabled = false

and doing a rolling restart of the servers, but Connect is still enabled. Doing a full stop/start of the 3-server cluster is really undesirable. Is there another way to remove Consul Connect?
