Return date for F2 Students

For F2 students, do we need to return to the “Bay Area” or “SF” specifically for early January? For example, if my home is San Jose and I stay there from now until early Jan, can I stay there 1/4-1/8, or will I have to be in SF from 1/4-1/8? Will there be an in-person activities 1/4-1/8 like covid testing specifically on campus?
