The only way to do that is to get a new judge, because this one has no integrity.
Actually, the ONLY way to “safeguard the integrity of these proceedings” is for every single one of the charges to be tossed out, immediately. They have absolutely no legal merit what-so-ever and are an affront to what used to pass for Justice in our Republic. Jack Off Smith should be disbarred and compelled to face a military tribunal for his acts of treason.
A good strategy is for Trump to keep quiet, and his posse stand and shout in all of the intersections of intercourse of United States Hiways and Biways.
