Question Sprite Atlas V2 on Unity 2021.3.9f1

My project is using sprite atlas v2 (experimental) and unity version 2021.3.9f1.
The problem is: if I have already created the sprite atlas (which packs a folder of images), then, if I want to change one image in this folder, the sprite atlas is always re-imported and re-packed. This takes a super long time.I am wondering if there is a way to skip all the stuffs about sprite atlas processing. I tried to disable sprite atlas in editor mode but it doesn't fix this problem. Any help or suggestions?

 

Any one have a solution?
