Thin end panel

I’m trying to gain an extra 5-7mm no fit a new free standing fridge freezer in a gap between the wall and the work top.

The run of cupboards go all the way down the one wall with a continuous wooden worktop. At the end is the fridge freezer then the wall (no skirting board).

I had thought of cutting down one of the carcasses slightly and the doors. Or getting something like a thin steel end panel to support the end of the worktop and cutting a price off the end of the wooden work top.

Any...
