I would probably reduce that hose length by 50% and tuck it in between the bars and the handlebar bag / attach it to the handlebar bag. Yes, it'll include a bit of bending down but you'd avoid this challenge altogether.
The current setup will interfere with your knees whilst pedalling which would bother me tremendously.
Another negative is the risk of the hose snagging something on the trail.
So I can drink whilst riding along- needs to be that length or I have to bend down.
