Yes. Deontological constraints, to the extent that they bite in practice, will result in you getting less utility than if magically you hadn’t had them at the moment they bit.
This is not an argument against deontological constraints, any more than it would be an argument against valuing welfare for men to point out that this will sometimes come at the cost of welfare for women. Everything has tradeoffs, and obviously if we impose a deontological constraint we are expecting it to cost utility at least in some circumstances.
