Yes.  Gmsh's equivalent to Warp (scalar) is View.NormalRaise.  I
attach a minimal example.

%<--elevation.msh
$MeshFormat
2.2 0 8
$EndMeshFormat
$Nodes

$Elements

$EndElements
$NodeData

$EndNodeData
%<--end elevation.msh

%<--elevation.geo
Merge "elevation.msh";
View[0].NormalRaise = 1;
%<--end elevation.geo
