I'm not aware of any issues where k3s ignores CLI flags.
Are you sure you disabled it on all the servers?
What is the output of kubectl get node -o yaml | grep node-args
?

You were right. I apparently missed one server, and forgot to close this issue. It's a bit tedious and counterintuitive having to set this flag on every server individually for it to have any effect. But that's a different story...

Oh, one thing that I've stumbled across in multiple occasions. The correct way to add the parameter is
--disable=servicelb
is that correct? Because in several places I've seen
--disable servicelb
or
--disable=svclb
and other variants, some with, some without equal sign. Some even with a trailing \ with an empty row below...

It's not ineffective - the controller doesn't run on the servers where its disabled. However If you leave it enabled on one, that server will run the controller which takes action on the cluster as a whole. I don't think it's a big ask to have servers configured consistently.
is that correct?
--disable=servicelb
and --disable servicelb
are treated identically. The golang flag parser treats values the same regardless of whether they're in the same arg separated by an =, or in a separate arg.
--disable=svclb
does nothing.

It's not a big ask in and of itself, but it breaks with the single source of truth principle. Just my two cents... Either way, my problem is solved. Thanks nevertheless!
