This is a much neater solution to the swing arm water ingress problem, just unscrew the stainless steel torx screw after power washing, a river crossing, or once a month to guard against condensation over Winter to let the water out. No rubber beak to get knocked off or pushed inside swing arm.

Although that raised boss looks an ideal location to put your bolt are you sure that it will be in the correct position to drain off any water - have you looked inside the swingarm?
There must be a reason why BMW drill the hole in what at first seems an odd place - and with the help of a special clamp/tool to aid positioniong - just to the side of that raised part.
2014 R1200GS LC , 42K miles , never taken off road and meticulously looked after as you can see by the condition
Look at the state of the driveshaft !It was corroded solid onto the final drive and could not be separated
No water was found inside the swinging arm whatsoever but clearly there had been serious water ingress in the past
Only solution was a new drive shaft and a new final drive
Hole drilled in swinging arm and one way rubber valve fitted and secured with some black Silcoset so it won't push out
Decided after the shock of seeing the state of the R1200 driveshaft to check my July 2022 R1250GSA
Plenty of Staburegs NBU30 PTM on the gaiter but not much lubricant on the splines so gave them a good coating of NBU30

Yes, it is dreadful, lucky it didn't explode ! Onahi's almost did
