QGIS 3x switching off label callouts

I need my label callouts switching off.

Basically I know how to do it. I am clicking on the label info ("Change label properties" I the main toolbar, then just switching off "Show callout".

The problem is twofold.
1 – I have to do it one by one
2 – If I switch it off, I am losing all the amendments done before (switching off brings my label back to beginning view) and I have to redo my changes.

Is there any change to switch label callouts for a whole defined text rule?
