Unity UI How to reduce Unity's instantiated UI batches?

I'm working on a simple Android game. And I have some enemies in my game that they has blood line and a text mesh pro for their names on top of their heads.

For doing this I made an UI image prefab and I put a Text Mesh Pro inside the prefab as a child.

And when my game scene load every enemy in the scene will instantiates their blood line with special name on their heads.

But my problem is that I wan't to reduce batches, because every blood line makes two batches and if I have 50 enemy in my scene , the number of batches will be to much. And I think it may affect the game's performance.

I want to know is there any way to reduce number of this kind of UI batches ?

I also say all of the instatiated blood line prefabs has same material.
