Hi, I am not aware of a function or of a plugin that does that. I would start by googling. A quick Google search has shown me this python solution. https://gis.stackexchange.com/questions/239129/shifting-display-of-overlapping-lines-in-qgis
It was created for an earlier version of QGIS with another version of Python. If would need to be adapted. If this is for a small project (but to big to do by hand) you could always just install a QGIS 2.XX version of QGIS in a virtual machine to see if it works. Then, you could ask help to adapt if to QGIS 3x. Maybe there is a plugin that already does this.
