Rating display in Talent Ratings page from Talent Review

When a talent review meeting concludes, a worker's profile is automatically updated with the calibrated ratings.

It happens after the reviewer submits his ratings and another time when the meeting is completed.

Is it possible to remove this automatic process?

Our client does 2 cycles of TRBs, one for the VP level and another one for the C-level.

They want to see on the Talent Rating page only the last rating, which is from the C-level TRB.
