Is there any way to create mountains by giving coordinates as inputs?

I’m trying to create mountains by giving the coordinates or measurements.
simply I need just giving the measurements and mountain will generate?
is there any way to generate?

You would have to implement the code for creating the mountain yourself - Unity does not provide this functionality. You should probably look into Perlin and/or Simplex noise generation to figure out convincing terrain can be generated. There is no “one-liner” solution.
