Yes, Alia Crum and Ellen Langer did a similar experiment to test whether physical exercise can actually be unhelpful if the person doesn't believe it IS exercise. They tested it on hotel housekeepers: gave some of them a presentation on how their work provides healthy exercise and the control group got nothing. The group that got the presentation improved on most of the parameters they measured. https://pubmed.ncbi.nlm.nih.gov/17425538/

It has also been tested with painkillers. If morphine is administered by a hidden IV after thoracic surgery patients don't experience as much relief as the ones who get it from a doctor (thus aware of it when it happens). They also tested it on Parkinson's disease treatment, hypertension and anxiety.

And as others have mentioned, there are also studies on nocebos, that actually generate negative effects rather than just blunting the effects of a treatment.
