How to load resources as read-only

Hello friends

I’m making a 2D game this time and I’m having a problem with memory management.

We’re using a few 4096-digit textures and they’re taking up too much memory

I’m not sure exactly when I load a resource, but it seems to take up about 120 MB

Based on this, it seems like the current resources.load() is loaded into the system memory as well

Is there a way to load this resource as read-only? I need both prefab and image.
