You may want to investigate "acoustic plaster" systems. They can be expensive, but you are dealing with a small area depending on how many separate rooms are involved. BASWA (
BASWA acoustic ® Sound Absorbing Plaster | BASWA Phon Acoustical Plaster) is one of the most well known brands, but there are other competitors as well.

Subject: Antiligature hard ceilings/acoustics
Hi everyone,
I am looking for great ideas! We replaced some lay in ceilings in some small behavioral health rooms with gyp board to make them anti-ligature, and as I anticipated, the rooms are now "echoy". Rooms are roughly 80-90 SF each with a 9'-6" ceiling, and they are carpeted. Everything else is painted gyp board. Any recommendations for an antiligature/durable solution?
