Can you change virtual to override? If so do it everywhere in this file.

Done for this method.

I don't want to touch other classes in order to not clutter this already pretty
hard to review CL that touches a lot of files.

I also removed the NOLINTs because they didn't seem necessary and were possibly
added because of the missing override?

There might be waterfall bots that complain if a file mixes using virtual in
override cases and using override. That happened to me a couple of times and I
had to revert, not sure if that is still the case.

I'm OK with virtual or override in all places in the file. Or this way if it
doesn't break waterfall.

I changed all methods to override and removed a few unneeded ones.
