SCOTUS said the moratorium exceeded the CDC's legal authority, but declined to strike it down given it was soon expiring [1]. (They also strongly suggested that if POTUS tried renewing, they would strike it down.) POTUS tried renewing. SCOTUS struck it down.
None of this is properly construed as POTUS ignoring SCOTUS. When SCOTUS struck down the law, POTUS obliged.
