schwab has told me that only shares in a margin account are loanable, and they will notify you to ask if you want to loan them. they will not loan them without asking, so you are fully aware and accept the interest. plus if your shares are loaned, you will not see them in your account, they are placed in a separate account to clearly track them. best way to ensure no loan happens is to deactivate margin on the account. still no concrete answer to the theory of putting a high limit sell order to prevent loaning, schwab always tells me that they will not loan shares without asking first..."not advice, call your broker"
