Limit Vaults to only be opened once no matter who opened it

im working on a datapack where you can achieve custom advancements that give you a reward. the reward is a vault that contains loot specified with custom loot_tables. now when you place the vault it drops the loot and waits until all of its loot has been collected. if it has been collected it destroys itself (since you cant in survival). the problem is that if the player does not collect all the dropped items, another player could open that same vault in the meantime. since you cant restrict vaults to only be opened once no matter who opens it (afak), i need a different solution
