Yes, the rules "explicitly prohibit promotion of/publicity services for work under the TV/Theatrical Contracts" including tours, personal appearances, interviews, premieres, and more. No red carpet, no Good Morning America, no social media, etc.

And the question has been asked and answered here several times, but for those still wondering if this impacts Broadway performances, the answer again is no, that's not covered under the SAG-AFTRA agreement.
"The guidelines, released on Thursday, state that the union’s 160,000 affected members will be prohibited from all principal on-camera work — including acting, singing, dancing and stunts — on top of off-camera work, such as voice-acting and narration. Also barred is background and stand-in work, negotiations for future services and any ancillary work for a struck production, among other things."
