How to make a structure spawn only once?

I'm trying to make a structure spawn once and never spawn again at specific coordinates. Any help?

 

I'm using Mcreator 2024.4 

version 1.21.1 NeoForge.

you can make the structure spawn with procedures, from a block, similiar to how sapplings work, except they check if a global variable is 0, and that goes from 0 to 1, if the structure-sappling successfully grew. all further sapplings can replace themselves with air, if the variable is already at 1
