The utility man, who skippered Wolves in their opening-day victory over Middlesbrough, was this week the subject of a speculative bid from Championship rivals Sheffield United.
Wolves promptly rejected the bid and head coach Nuno was emphatic when asked if Coady might possibly leave if the price was right.
"Conor is going to stay with us," he said at Friday's pre-Derby press conference.
And in reply to being asked if that was categorical he replied: "(It's) finished."
Coady is out of contract at Molineux next summer and it's believed Wolves hope to tie him down to a new deal in the coming weeks.
He was a mainstay for Wolves during pre-season in a new centre half role.
Sheffield United already have one former Wolves centre half at the club in the form of Richard Stearman, who moved to the Blades from Fulham in the summer.
Their boss Chris Wilder went public with United's Coady bid after Tuesday night's Carabao Cup victory over Walsall but refused to say if it had been accepted or rejected.
