The 62-year-old has rotated his pack during the Confederations Cup, with Xavi criticised after reports he voiced his displeasure at the line-ups and undermined his trainer's authority.
But after Del Bosque and assistant Jose Grande insisted their playmaker had always been mindful of his place, the Barcelona star himself underlined that he has never once attempted to question decisions regarding personnel.
"I wouldn't dream of telling the manager who I have to play with," Xavi emphasised to Spanish television channel Cuatro.
"I've never done it, and never will as long as I live. Everyone has a voice here, and no one is above anyone else.
"We always speak with the gaffer about what's best for the team, but not about who should play. Never about that."
La Roja are currently preparing to face Brazil in the Confederations Cup final at the Maracana on Sunday.
Del Bosque's men go into the game after beating Italy 7-6 on penalties, while the tournament hosts dispatched neighbours Uruguay 2-1.
