[SyncVar] protect Cheat Engine

Is there any solution to protect [SyncVar] from Cheat Engine? for example:

 [SyncVar(hook = "OnMoneyChange")]
     public float money = 500.0F;
  
 public void OnMoneyChange(float updateMoney){
         money = updateMoney;
     }

If I use Cheat Engine, it easy to change it and then buy something for example in my if money < itembuyprice

 if(money < itembuyPrice){
                 inventory.DontAllowBuy();
                 }

with this you can bypass that if, your SyncVar goin to "-" float, like -500$, but the Cheat Engine shows 100000$ and allow to buy. Thank you
