Inventory check in advancement

I try to check, if the player has more items than (x>64) without nbt (because it causes lags). I tried to use inventory_changed trigger, but it can't count more.
For example:
 "trigger": {
      "trigger": "minecraft:inventory_changed",
      "conditions": {
        "items": [
          {
            "items": "minecraft:obsidian",
            "count": 1728
          }
        ]
      }
    }
