Of course, you can.
You can specify spec.service.apiPort and spec.service.konnectivityPort fields to change the default node ports: https://docs.k0smotron.io/stable/resource-reference/#k0smotroncontrolplanespecservice

Understood because, i haven't configured the konnectivityPort it was blocking me from having a second CP in pods :(
Just tried it out and it didn't work @makhov :( update
kuberouter keep crashing because of failed readiness :(
i was looking to switch to calico but haven't found in the documentation how to do it properly
Might be a good idea to document that , what do you think @makhov ? should i PR ?

any hints about why kuberouter keeps crashing, complaining about failed readiness probe @makhov ?

Yeah, it looks like it's due to the bug fixed in #638. It should be fixed in k0smotron v1.0.1. Feel free to re-open the issue, if the problem still exists
