The best is to just do it at the appropriate time and not depend on bitcoin ATM. You can see many options for United States dollar on Bisq.network and Hodlhodl.
Is there an appropriate time though because it's like you'd be monitored for every transaction you make and when you do, it's like they get a notification. I don't use these ATMs but it would be appreciated if it's use gets scrapped because it's clearly causing more harm than good.
You know the people see bitcoin ATM close to them and see that it will be fast, this has been the reason they prefer to use the ATM instead. What I meant as the appropriate time is to exchange the coin to fiat or the fiat to coin in surplus and it should not be in a way that you will have to do things in a hurry. You can make use of those decentralized exchanges instead if you are the type of person that I described, to do it in advance and not in a hurry.
