This isn't as simple as other unitframes since the raidframes are dynamically created and shuffled around as needed to facilitate sorting and filters. Also, the handling of the heal prediction and absorb bars are passed to a centralized function that would affect other unitframes using the same template.

If this doesn't bother you, you can try this.

local oldfunc=CompactUnitFrameUtil_UpdateFillBar;
function CompactUnitFrameUtil_UpdateFillBar(frame,previous,bar,...)
    if bar==frame.myHealPrediction or bar==frame.otherHealPrediction then
        return previous;
    end
 
    return oldfunc(frame,previous,bar,...);
end
 
hooksecurefunc("CompactUnitFrame_SetUpFrame",function(frame)
    frame.myHealPrediction:Hide();
    frame.otherHealPrediction:Hide();
end);
