1050 Chain Guard Replacement

@English Phil What bike mate. And a picture of the area would be helpful. I have never had to remove wheel to get a chain guard of

 

I would go for the Carbon FBR rear extended hugger and chain guard, the parts are top quality. As regards the removal of the chain guard it can be done in situ, however given the fastner is very hard to get at and time consuming, especially putting it back, it is far easier to just remove the rear wheel, it only takes a couple of minutes, and you wont risk damaging the torx head.
