If I understand correctly, then yes. You can edit ~/.wbarconf or use the GUI tool tc-wbarconf to add the --nanim option (number of animated icons:1,3,5,7,9,...).
Default is --nanim 3 , I changed it to --nanim 1 .
( --zoomf 0.0 might be useful, too.)
Then execute wbar.sh in a terminal to restart wbar.
