Ryan Giggs will remain on leave for the start of Wales' World Cup campaign with Robert Page taking caretaker charge again.
Manager Giggs, 47, was arrested on suspicion of assault at the start of November and last month had his bail extended until 1 May.
"The Football Association of Wales and Ryan Giggs have mutually agreed that he will not be involved in the upcoming international camp," said an FAW statement.
"Robert Page will take charge for the next three matches against Belgium, Mexico and the Czech Republic and will be supported by Albert Stuivenberg as was the case during the last international window in November."
Wales start their World Cup qualifying campaign in Belgium on 24 March and host the Czech Republic in Cardiff six days later
Wales' preparations for the delayed Euro 2020 tournament this summer have also been disrupted by the departure of chief executive Jonathan Ford after a vote of no confidence was passed by the FAW council.
Ford's departure was announced on Tuesday and he will leave his position on 31 March.
The marketing and sponsorship expert had been at the FAW since December 2009 and was widely credited with lifting the association's profile and increasing turnover.
But rising tensions behind the scenes over a number of issues resulted in the council passing a vote of no confidence by 26 votes to five on 22 February.
