If you are really sure that you want to override this behavior here are the necessary steps, this will ensure you can later easily reconnect to the vCenter Server:
Please ensure to NOT remove the ESXi host from your cluster inside the vCenter Server, as then the resetup might be more complicated.
This process shall normally ensure that all setups like Distributed Switches, Storage Cluster etc. work as designed.
