Yes and No. If you open the profile of a conduit, you can make a new profile with the desired break in slope, then make this profile the active profile. However, the hydraulic analysis will still treat the conduit as a single slope from the start invert to the stop invert.

Thank you Robert for the information,

If you want to correctly model a change in the gradient of a conduit hydraulically, then you need to insert a transition node in the conduit, to split the conduit in to two pieces. You can then set the invert of the transition node appropriately to change the gradient of the conduits on either side.
A transition type of node (as opposed to a manhole type for example) is used where something changes in conduit geometry, such as the shape, size, or gradient. It doesn't have to be a physical chamber that you can climb into.
The symbology of the transition node could be a cross in plan, and a tiny ball in 3D, such that it's smaller than the conduit and not therefore noticeable. I think the workspaces that we ship with the software include an example transition node.
Thank you Jonathan for your information,
Actually i tried this method with using a null node just to control the IL at this point , but at that point as you can see in the image, the conduit has a deviation and need to have curvy link,
Plus the ORD will analyse it as 2 separates conduits that is not our case,
