Can a retained attorney be discharged from trial for failing to attend defendant's trial?

defendant. (See People v. Maciel (2013) 57 Cal.4th 482, 512 [court may consider whether retained attorney is inadequate or has an irreconcilable conflict with defendant when deciding if discharge would disrupt orderly processes of justice].) Witnesses had been subpoenaed, a trial court had been assigned (thereby rendering that court unavailable for other ready trials), and jurors were ordered for defendant's trial. Despite the parties' and trial court's readiness to proceed, defendant requested to substitute in an unprepared attorney whose participation would have inevitably continued trial for an unspecified period of time.
