Teams typically won't run the kiel probes outside of testing. The only things they are likely to keep during a race are a few static pressure taps in the front wing and the floor to monitor the aerodynamic performance during the race (i.e you can evaluate the severity of damage to aero parts by looking at the pressure taps on the floor). It also lets you rule out aero degradation when handling issues occur.
There are some photos out there of the F1 floors and you can see the pressure tapping inside the floor from the b-side.
