A 4×4 quad trail between here and Nuuk was completed in 2021, see https://travel.stackexchange.com/a/175910/2509 for a map and links in that post for more information.  This quad trail is not visible in the latest satellite imagery yet (either the imagery is too old or the trail is too faint).  The trail is drawn on https://listservices.dataforsyningen.dk/#/map/WMS/wms/gl_aabent_land but I don't know if the license allows to copy this.
