It's unfortunate that you need to refer to terms and conditions with hotel loyalty programs, but it is what it is. Always be aware of the terms and conditions before making a booking.
I just did a spot check on the App for the Bulgari Hotel in London which I know does not participate in Marriott Bonvoy program and at the top of the Hotel Information pane just below the hotel name, address and location map are the words
This hotel doesn't participate in any loyalty programs
Unfortunately I can't post a screen-cap as my phone is old and semi-broke (much like its owner) and the screen-cap function does not want to work.
Granted it's not in bold text and granted it's not evidence that Ritz-Carlton Reserve properties such as the Dorado displayed a similar message prior to being brought fully into the Bonvoy embrace (death grip?

) but it does demonstrate an effort on the part of Marriott to make such information available to those who are more thorough in reading the details of the particular offer they are booking.
