Healthcheck strategy for a MultiProject deployed in different servers

Can I setup a thread pool only for a healthcheck endpoint. Since each sub-project is deployed to in a group of servers, the AWS healthcheck agent keeps opening new connections.
Would it be possible to just have one dedicated pool, which won’t interfere with the apps themselves?

Thanks

Upon close inspection, I’ve realized that Result(OK) or Result(NOT_FOUND) has keepAlive connection enabled by default, so I believe the issue must be on the client side.
