How can I preload and pre enable only the assets I'm getting from Api

I have developed an online fruits store and I’m getting tags from api for the fruits assets which are in stock and will be shown to the user.
But the problem is that in Mobile, since it is hanging a lot when trying to load a lot of fruits at once, the app crashes on the mobile.
Is there a way I can execute my script that basically fetches the tags and matches them with the assets in the scene and enable them during the preload state?

I tried loading the script before engine but It didn’t enable the assets.

I’m confused.
