How to temporarily disable pose transformation in Weight Paint mode? Is it possible temporarily disable pose transformation when in Weight Paint mode? Like it happens when a mesh is in Edit mode?
If it's not possible temporarily then maybe I should employ some standard tactics like somehow saving pose transformations into a temporary keyframe, clear all transformations in the original keyframe, weight paint, and restore all pose transformations from the temporary keyframe?

Select the Armature. In Object Data Properties, enable Rest Position.
Don't forget to re-enable Pose Position once you're done.
