According to the SAFe 6 Scrum Master documentation, one of the elements on the Scrum Master/Team Coach responsibility wheel is to facilitate PI Planning. PI Planning is a two-day event where all the teams and stakeholders of an Agile Release Train (ART) collaborate to align on a common vision, define and commit to the PI objectives, and identify and manage risks and dependencies. The Scrum Master/Team Coach facilitates PI Planning by 1:

Helping the team prepare for the event, such as reviewing the business context, vision, and backlog, and creating draft plans

Supporting the team during the event, such as facilitating breakout sessions, resolving issues, and ensuring alignment and collaboration with other teams

Assisting the team after the event, such as finalizing the plans, updating the PI board, and conducting a retrospective

Facilitating PI Planning is one of the ways the Scrum Master/Team Coach helps the team and the ART achieve their goals and deliver value.
