Is it possible to lock only the thumb wheel?

I shoot almost always wide open, and have very little need to adjust aperture. Is it possible to lock just the thumbwheel so I don’t accidentally adjust the Av while walking around? I see it’s possible to lock BOTH wheels.

Bonus question: It seems like there’s no way to adjust the function of the thumbwheel *button*. When I accidentally click it, again, while walking it gets bumped against my hip, it enters into program mode, which is bad when I’m using the thumbwheel thinking I’m adjusting aperture.

I think it is called Gaffer tape, and it is not in the menu 😂

Noted. Haha.

Or a different carry approach. For instance, a different strap attachment, e.g., one lug and bottom plate, so that lens points down rather than outward, without back of camera against hip. This is particularly useful for longer lenses.  I use this approach with a Peak Design strap and its simple attachment anchors, mostly to keep the lens from protruding outward and banging into things.

Happens to me to, very annoying

I think @Jeff S is on to something here. The way you’re carrying/handling the camera sounds like an opportunity.

To have to lock the main control wheels on any modern camera either indicates a major design flaw or a handling issue. In this case I’ve never had an issue with an SL or SL2-S accidentally turning either control wheel or accidentally pressing the thumb wheel. 

I carry the camera with the strap across my body, sling style, on my hip most of the time. I don’t even have to use a bottom attachment point to have the camera sit lens down.

+1, works for me also, SL with zooms since 2017

I should add that I totally understand the idea that additional functionality (such as the ability to individually lock out control wheels in software) seems like it’s harmless. 

On the other hand, adding too much functionality chips away at the simplicity of the camera and demonstrates poor design.

It’s my opinion that the primary controls should be designed in a way such that they need no lock out. Another way to look at this is with the pre-“modern” interface cameras. Would you want a lock on a lens’s aperture or focus rings? Would you want a lock on the shutter speed selection? Would you want a lock on the shutter release? These key controls need to be designed to just work properly. If the “modern” design made them less effective, it should be scrapped on any camera. The SL system has these controls designed right. They’re mode dependent, well placed and the haptics are excellent.
