No, doing so will cause issues with the integrity of the original segment and the frozen segment.
The guest upload portion that generates the values for a freeze from segment, only occurs when the segment is created, and not when they're edited. This means that the freeze from segment can't be changed after it is initially saved, and doing so will cause issues with the integrity of the segments.
To avoid any possible issues, it's recommended to create an entirely new segment instead of trying to implement any edits.
