Inside of your map folder (e.g Resources --> fivem-map-hipster) There’s a lua file you can edit that has all the spawn points (e.g Resources --> fivem-map-hipster --> map.lua) From there delete every spawn point and grab the coordinates for your own spawn point you can also choose the model for your character to spawn with.
spawnpoint 'a_m_y_hipster_01' { x = -802.311, y = 175.056, z = 72.8446 }
^^^^^^^^^ -- Model ^^^^^^^^^^^^^^^^^^^^^ -- Coordinates for spawn
You can use this to grab and save coordinates: Click Me
Hope I helped!
