Only mod that alters spawn points for players that I know of is singleplayer only, but as for the coords, have a look here:
https://valheim-map.world/?seed=pr8lXMyBeL&offset=288%2C-320&zoom=0.219&view=0&ver=0.207.20

enter your map seed and hit "Go".
You also can enable/disable multiple markers, the ones you might be interested in might be the "Villages", the ones where the ruined remains of a small number of huts are. NOT the Draugr Villages!
