Pipe are going from above ground to underground it is having slope if i maintain a single elevation it is clashing with a trench
so my question is it possible to change elevation in U/G pipes. Some body said we cannot change elevation in U/G pipes

Is it possible? Yes.

Is it a good idea? No idea as you've given us no details or drawings

Needs a sketch or drawing to understand what your issue is.

Not following exactly what you you said or what your question is but...

If the pipe is pressurized, then nothing is keeping you from changing the elevation of buried pipe. Up, down, whatever you need to avoid conflicts.

If is is not pressurized, i.e. a gravity drain such as sanitary or storm drain, then you're a little more restricted in that as long as the flow goes DOWN in the direction of flow you're golden.

You do want to be mindful of any future structure that will be built above the pipe (foundation, driveway, road, etc) and not go too shallow, such structures can damage shallow piping. Conversly, going too deep gets costly.
 
The depth of underground piping is typically set to minimize the construction cost. Important considerations when setting the pipe depth includes the frost depth (where freezing of the pipe contents is a concern) and physical damage (pipe is buried at a minimal depth to prevent).

Typically underground piping follows the natural terrain but the depth of piping may be adjusted to clear obstructions.
 
Always watch out for engineering offices guided by "somebody who says" .....
