Does electrical conduit in a cinderblock wall need to be covered before being plastered over?
NM can be in the hollow cavity’s of block walls but not embedded in a cutout.
When run in block walls, if exiting the wall conduit would be needed on the outside unless a surface covering is provided (a furring strip on either side with 1/2” plywood or Sheetrock) is another way to do it. Your actual work might provide more detail.
