Export model with displace modifier to Unity

Hi, I’m new in the forum and in the 3d game desing.
I’m making a game in Unity and for the 3d part of the project, I’m using Blender.
I have several models in Blender that have a displace modifier.

Before exporting them to Unity, do I have to apply the modifiers?
Will Unity see my displacement map after I’ll drag the texture in the inspector?

Thank you very much for any help
