I'm changing out my kitchen ovens and the new one
needs an additional 3/8 to 1/2" of side clearance. It is
a sheetrocked wall, 1/2". Because it will be hidden
doesn't matter about looks. The oven is rated to be
installed in wood cabinets with essentially zero
clearance. Some options that come to mind:

1 - Remove the drywall and trim the studs down by 1/2"
over the full height of the wall using a router? Other ideas?
Then re-drywall. The wall is non-load bearing.

2 - Just leave the one section of hidden wall where the
ovens are without drywall. It's just a short wall, not open
to anywhere above or below and will never be seen.

3 - Same as two but use sheetmetal to cover the studs.

4 - Other ideas? Is there some other product that
is thin and can be used instead of sheetrock for
something like this?

Thanks for any input!

Ideas 2 and 3 seem like they would probably work if you want to do them.

For Idea 1, maybe another option would be to: remove the existing sheetrock;
sister 2x3 studs next to the existing 2x4 studs; cut the existing 2x4's down
to the level of the 2x3's with a circular saw and/or Sawzall; the
re-sheetrock with 1/2-inch sheetrock. Or, if you have access to both sides
if the existing wall, maybe tear it down and rebuild it with 2x3's and
sheetrock both sides with 1/2-inch sheetrock.
