Toggle «Show ranges of bar numbers multi-bar rests» off for single flow

I have a project with three flows. In the two first flows, I want ranges of bar numbers to appear under multi-bar rests. In the third flow, it would create confusion because of polymeters – I start the bar numbers only when all players share the same barlines and meter.

Hiding bar numbers at the staff and changing the bar numbers works. But I can’t seem to be able to remove the ranges of bar numbers under multi-bar rests – not even by changing the colour or opacity in Engrave mode. Is there a way to do that in one flow only?
