Got a 2014 golf 90 tsi with a CSXA engine. Planning on doing the timing belt soon as it's done 105,000kms.

Looking online at the procedure all off them talk about locking out the cams on the gearbox side and removing the cam gears. If I am only doing the timing belt, is it still necessary? Can I not just set the engine to tdc remove the tensioner and idler then slip the belts off?

First time working on this engine in particular , but have done numerous cam belts on Japanese engines before, most of which have been relatively simple.
