the part of the fender liner is pressed right against the interior cabin liner so maybe banging the liner might be minimal but enough then there is really not a place to zip tie but....I will have to experiment.
Used to “NorCal Nick” the fenders on NNBS trucks, not sure if you can use it on these new gen.
You can pick up 1/4” wheel spacers at the auto part stores for cheap. Hardly noticeable and will take the tire off the sway bar.
FWIW I’ve got sway bar rubbing on my stock 16.
