Yes, I managed it. I followed the instructions of the post mentioned above:
Setting environment variables is a standard windows procedure. Search from the start menu for "Set environment variable" and you will see a window pop up that says "System Properties", in here you can click the button "Environment Variables", then "New", then enter the name PBI_diagramTableThreshold, and then the value (100 for example). Press okay until the dialogs are gone, and then start a new instance of Power BI Desktop. The limit should no longer apply.
