"c) Hold Close Limit button for 5 seconds until LED flashes
7) Leave fabric unrolled, inspect for fabric flaws, then return it to eye level.
8) Press Raise button on keypad to roll fabric – check for telescoping
9) Press Close button on keypad to unroll and ***shim*** (if needed, repeat steps 6 and 7 until correct)"
... can you help me with a synonym of shim in the context?

See explanation below...
The verb 'shim' has nothing to do with the 'unroll'!
It just means you have to use the electric controls to unroll the blind, then check its positioning in some way, and add thin packing pieces to make fine adjustmens of whatever is being checked (NOT the blind itself, apparently!)
The 'shim' here doesn't necessarily mean 'accurately-sized' pieces of metal as in normal engineering, but it's just a formal-sounding word meaning 'to adjust by packing with add-in pieces' --- almost certainly thin sheet material, to allow fine adjustment.
It is not clear to me from the amount of context you've been able to give exactly WHAT needs to be checked and then packed; I assume it must mean that you have to adjust the mounting position of the blind brackets (etc.) so that when fully unrolled, the blind sits evenly at the bottom, for example...

to add small wedges
Shim
A small wedge of something meant to fill in a gap or adjust something.
For example, a camera which has been subjected to a blow might have a slightly deformed lens mount. A thin metal shim can be cut and inserted behind the lens mount to adjust the mount to film plane distance and compensate for the damage. Or a camera battery or spool of film which doesn’t fit the camera cavity properly and is too loose may need a simple cardboard shim to be wedged in properly.

What they want you to do here is to first fully unwind the shade (and inspect it for flaws, but that has nothing to to do with the shimming), and then fully wind it back onto the roller. Then you should check to see whether it rolled up straight. If it doesn't roll up straight, the edges will gradually shift to one side as it rolls up, which is what 'telescoping' means here; it's the same thing as what happens when you roll up a carpet as a slight angle. And if the shade doesn't roll up straight, that means the roller is not exactly level, so you have to insert shims somewhere (probably underneath a bracket holding one end of the roller) to level the roller. Unfortunately, the instructions don't say anything at all about where the shims should be placed (a fairly severe shortcoming; I suppose it's a sort of intelligence test...).
