for me. Is there a way I can detect the ground and mark it as free ?

Not all ground would become an obstacle, just the ground lower than the current ground the robot is on. But if this also an issue, you can remove the "Grid/MinGroundHeight" constraint, and set "Grid/FlatObstacleDetected" to false (all planes will be empty), but the robot should be careful to avoid unknown.
