Is it possible to hide / remove the Undeposited Funds radio button from Customer Payment record, without hiding the Account field underneath it?

refer to my previous answer should be the same process

You can only hide the Account field, not Undeposited Funds field. When you hide the Accounts field, it hides both of them, I just want to hide the Undeposited Funds radio box?

Just a reminder you can set the default behaviour on the Payment Method and then move these fields to another subtab if you aren't successful in your other endeavours.
