I'll say it again: since the SCOTUS intends to slow-walk a decision on presidential 'absolute immunity', Biden needs to announce RIGHT NOW that he's dissolving the SCOTUS effective 2 weeks from the time of the announcement, at midnight, intending to appoint an all-new roster of his choosing, as well as replacing all state-level judges, also of his administration's choosing.
If the SCOTUS, on the other hand, suddenly finds they do have the time to make a decision on presidential immunity before that deadline, well maybe Biden won't do it, after all.
