. 10000x 10000y 500z but my map will be only 100x 100y and 500z at the time ? will this have impact on game performance or will it have memory footprint etc. or it will only allocate as much memory as needed ?

apparently one option is to use a Recast Navmesh

Modify NavMeshBoundsVolume in C++

To be Honest I dont know why you would ever need to attach a Navmesh to anything. If you just want to create a Navmesh around a Actor use Recast navmesh.
