If you are discontinuing a non-required notice that your customers have come to expect it may be confusing to your customers if they don’t receive the notice from you. I don’t know of any requirement that says you must notify your customers that these will be discontinued. With that said, we have seen that many of the complaints regulators receive are due to a lack of communication between the bank and customer. It might be worth informing your customers when they will receive notices going forward.
Another thing to note is that you want to make sure these loans aren’t covered under 1026.20(c) and its commentary.
(1) Coverage. (i) In general. For purposes of this paragraph (c), an adjustable-rate mortgage or “ARM” is a closed-end consumer credit transaction secured by the consumer’s principal dwelling in which the annual percentage rate may increase after consummation.

Commentary 1026.20(c)(1)(i)-1: In general. An adjustable-rate mortgage, as defined in § 1026.20(c)(1)(i), is a variable-rate transaction as that term is used in subpart C, except as distinguished by comment § 1026.20(c)(1)(ii)-3. The requirements of this section are not limited to transactions financing the initial acquisition of the consumer’s principal dwelling.
Note: The reg and commentary provide a few exemption to this coverage rule.
