Is there a way in QGIS to transform a Polygon layer (shapefile) to a Line layer through "Virtual Layers"? In case there is how could I in addition to making the conversion also avoid duplicate geometries in this virtual layer, so that polygons that share boundaries with each other will generate only a single line when converted to lines?

    It is not straight but it is possible, check this https://gis.stackexchange.com/a/382382 for instance, there one step forward was done, so you need to get the interior and exterior rings (depends whether your polygons posses holes). However, I want to ask why do you want to make your life a bit more complicated when QGIS/GRASS geoalgorithms are marvelous for solving exactly your problem? – Taras Jun 02 '21 at 18:23

You will get best results if you install Grass GIS together with QGIS and use the processing tool v.to.lines.
